What diseases do hamsters have?


The hamster is a tiny little animal, masterfully attracting your attention and causing emotion: the way he sleeps, eats, plays, I want to pick it up and feel this warm fluffy lump in the palm of my hand. Put a wheel in the cage, attach tunnels to the cage, put the hamster in a walking ball - this pet will amaze everyone with its mobility, agility and endurance.

For normal growth and development, the hamster needs carbohydrates, proteins, fats, vitamin and mineral complexes and clean water. If necessary, veterinary specialists-ratologists at the Vetmaster Veterinary Center will help you find the right diet for your pet, taking into account the needs and depending on the time of year. Of course, at home you can do it yourself, but you must take into account the fact that the feed must be fresh and varied, contain not only plant components, but also components of animal origin. And for the normal functioning of the gastrointestinal tract and a full wipe, and grinding the teeth, the diet should contain coarse fibers, twigs and special treats.

Common Hamster Diseases

It is worth raising the question of the most common diseases encountered in hamsters, their symptoms, outcomes and possible ways to resolve them safely.

Vitamins. Due to a lack of necessary sources of vitamins in the diet, hamsters develop various, in some cases, irreversible pathologies. The spectrum of symptomatic manifestations of these pathologies is different: weakness, problems with gums and teeth, problems with eyes and skin, problems with joints and skeletal muscles, impaired functions of the gastrointestinal tract and central nervous system.

If these symptoms appear, you should immediately contact a veterinarian-ratologist of the Vetmaster Veterinary Center. The task of our specialists is to correctly recognize and diagnose the type of pathology, select the appropriate treatment and adjust the diet of the animal in order to avoid such problems in the future.

Infectious diseases of hamsters symptoms and treatment. Caused by pathogenic micro-agents (bacteria and viruses) that can invade the body from sick animals, when bitten by various insects, through infected feed, water, or care items.

Bronchosepticosis. Airborne bacterial infection. Symptoms: runny nose, serous-mucous or ichorotic discharge from the nasal cavity, sneezing, snorting, ruffled hair, loss of appetite, wheezing in the lungs. Treatment: isolated content of healthy hamsters from patients, sulfa drugs are prescribed, drug dosages are prescribed only by a veterinarian!

Pasteurellosis. Ways of infection are airborne, contact. Symptoms: runny nose, septic effects, hemorrhagic inflammatory processes, pneumonia. Treatment: with timely treatment, the administration of penicillin antibiotics is effective.

Pneumonia. Viral infection. Ways of infection are airborne. Symptoms: pneumonia occurs, apathy, wheezing, the animal does not eat, heavy breathing, frequent, coughing, purulent discharge from the nose, eyes. Treatment: Prescription by the veterinarian of oxytetracyclines, sulfa drugs and vitamins.

Rodents have many acute respiratory infections. Symptoms are very similar to some symptoms of other infections, so it is recommended to consult a veterinarian for the correct diagnosis and the appointment of adequate treatment. In Vetmaster, qualified specialists and a modern diagnostic base of the veterinary center will help you with this.

Enteritis. Mixed infection caused by bacteria of the genus Escherichia and campylobacter. Contact pathways. Symptoms: refusal of food, watery diarrhea, increase in general body temperature. Treatment: neomycin, tetracycline, enterosorbents, as a rule, treatment is ineffective, due to the fulminant course.

Unfortunately, there are a number of infections, the terminal stage of which is the death of a rodent, the treatment of these infections is usually ineffective, such diseases as rabies (extremely rare), Aujeszky’s disease, Tizzer’s disease, colibacillosis, lymphocytic choriomeningitis, listeriosis, pseudotuberculosis, paratyphoid, or salmonellosis, tularemia, viral encephalomyelitis. For detailed information about these diseases and consultation, you can contact a specialist-ratologist of the Vetmaster Veterinary Center.

Fungal Hamster Disease Symptoms and Treatment

Fungal diseases of hamsters symptoms and treatment. Infections caused by spores of various kinds of fungal flora. Diagnosed only by veterinarians. Vetmaster veterinarian center doctors will help diagnose fungal infections and prescribe the correct and effective treatment for your pet, consisting in local and systemic antifungal therapy and immunostimulation of the animal’s body. Of the existing fungal infections, the most common are:

Actinomycosis. Called by the so-called radiant fungus of the genus actinomyces, which enters the body of a hamster with infected cereal plants. Symptoms: damage to the bones and muscles of the jaw, gums and teeth, the junction of the incisors is shifted and they are not erased correctly, discomfort occurs while eating.

Dermatophytosis. Called by fungi of the genus trichophyton and microsporum. Danger to humans. Symptoms: gray, dry, flaky areas of baldness on the body of a rodent, itching, scratching.

Scab. It is caused by a fungus of the genus Achorion. Symptoms: loose profuse peeling in the ears and eyes, the presence of gray small vesicles, then peels and sores, itching, scratching.

Parasitic Hamster Disease Symptoms and Treatment

Diseases caused by external (ectoparasites) and internal (endoparasites) agents.

If the hamster develops itching, scratching, loss of appetite, the owner may suspect the presence of external parasites in his pet, some types of parasites can be detected with the naked eye on the hair, skin and ears of the hamster. These can be fleas, lice, lice, ticks and others. In this case, the radiologist prescribes contact insecticides in dosages of a rodent safe for health.

If the hamster feces softened during bowel movements, mucus, blood or even fragments of internal parasites are present in the feces, then it is worth suspecting the presence of internal parasites in your pet (various types of helminths, coccidia, and others). It is necessary to consult a radiologist in order to diagnose the type of parasite and the appointment of antiparasitic drugs.

Non-communicable hamster disease symptoms and treatment

Along with the above pathologies, hamsters often have severe problems with internal organs (non-infectious diseases of internal organs), diseases caused by environmental influences (poisoning, heat stroke and hypothermia, injuries, etc.), as well as immune-mediated diseases (allergies, idiopathic symptoms And so on).

In any case, it is necessary to understand that hamsters in the natural habitat are victims of predatory animals, therefore, the behavior of them is supposed to veil signs of the disease. Because of this, it is very difficult at home to determine how a hamster really feels. If the baby is hiding from the owner’s eyes, hiding, doesn’t want to eat delicious food and delicacies, avoids the usual games, if the hamster’s hair has become dull, looks untidy, and his eyes are watery, this is a clear signal to the owner that the pet is sick. So you can’t delay visiting a doctor or self-medicating, it can cost a beast a life!

At the Vetmaster Veterinary Center, qualified ratologists will conduct an appointment who will help to adequately assess the health status of the pet, correctly diagnose hamster diseases and prescribe effective treatment that will help save your pet's life.

What a healthy hamster looks like

Before you start treating your own hamster with might and main, you should find out in detail how a healthy animal looks after all. It is often quite simple to identify, since a healthy hamster is cheerful, playful, and also actively contacts a person.

However, in some cases, the activity of the animal does not always indicate the level of its health. Therefore, before carrying the pet to the veterinarian, carefully examine it.

  • clean and dry eyes, without any mucous secretions, with a bright shade and shiny surface,
  • dry, clean, shiny and uniform hair,
  • calm and uniform breathing, without sharp breaths or other disturbances,
  • short or medium long nails with a solid surface and a homogeneous structure,
  • dense body and elastic tissues,
  • good appetite, and always strive to stock up on any available food,
  • highly active, the animal is curious about the world around it.

What does a sick animal look like?

So, we already know what a healthy rodent should look like. Now you should deal with the cases in which you need to sound the alarm and at all costs be sure to visit the veterinarian.

To make an accurate diagnosis, with the development of any dangerous diseases in a hamster, is not so simple.

However, a closer look at the health of the pet should be when it is observed:

  • poor appetite, up to a complete rejection of food,
  • decreased vitality (lethargy),
  • constant hibernation throughout the day,
  • sudden weight loss, up to uncharacteristic thinness,
  • aggressiveness,
  • purulent discharge from the mucous membranes,
  • change in the structure of the eyeball,
  • one or both eyes narrowed
  • dirty genitals
  • dirty, dull and sloppy hair, tousled or with bald patches.

What hamsters get sick

Hamsters are animals in good healthHowever, this does not mean at all that your pet is absolutely protected from the development of any ailments, since modern veterinary medicine knows many diseases that are quite common in domestic hamsters.

Let's deal with each of them, as well as how to treat them in more detail.

Tooth abnormalities

Tooth abnormalities - This is a severe hereditary pathology of rodents, which occurs quite often. It is a congenital defect, due to which an excessively active growth of teeth is observed in the rodent.

As a result of this, the teeth prevent the animal from eating normally, and also cause pain and inflammation. Sometimes tooth abnormalities can be an acquired pathology, in which case it occurs due to a lack of solid feed in the animal's diet.

The main symptoms are: profuse salivation, abnormal behavior, refusal of food, as a result of which there is a sharp decrease in weight, elongated teeth that abut against the upper lip.

Treatment: pathology is eliminated by adjusting the diet (increasing the amount of solid feed) or using special sharpeners for rodents. In severe cases, it is necessary to produce artificial cutting of teeth using a drill or side cutters in a hospital.

Aujeszky's disease

Aujeszky's disease (false rabies) is an infectious disease caused by a DNA-containing virus, which is one of the varieties of herpes viruses.

In most cases, the virus spreads through infected physiological secretions of sick animals with food, litter or in direct contact. The disease is accompanied by damage to the central nervous system, as well as all related disorders.

The main symptoms are: itchy skin, accompanied by severe bloody scratches on the body, anxiety, aggression, a sharp change in behavior.

Treatment: treatment of the animal is carried out in a hospital using hyperimmune serum and gamma globulin. A complete recovery of the rodent is possible only in the first stages of the disease; in advanced cases, paralysis of many physiological functions of the body develops, which leads to the death of the animal.

Inflammation of the cheek pouches

Cheek pouches are a paired muscular organ in which rodents accumulate and transfer food from the prey to their nest. When particles accumulate, as well as due to damage to the inner surface of the sac, a rodent can develop a serious infectious lesion of the tissues of the organ.

Untimely treatment of this disease leads to disruption of the nutrition process, and can also cause sepsis and death of the animal.

The main symptoms are: the first sign of inflammation is loss of appetite, up to a complete rejection of food, a sharp decrease in weight in a rodent, as well as its increased attention to its own cheeks.

Treatment: to eliminate inflammation, it is necessary to clean the mouth and bags from food debris, and then periodically treat the inner surface of the organ with all kinds of antiseptics. General therapy is a rather complicated process, therefore, it is carried out exclusively in a hospital.


Helminthic infestations are found in almost every mammal, and domestic hamsters are no exception.

Most often, rodents are affected by tapeworms (Hymenolepis nana, Hymenolepis diminuta), but among parasitic organisms one can also find nematodes (Syphacia obvelata, Syphacia muris).

Often, infection occurs when infected water and food are consumed, but helminths also enter the body of the hamster with the help of an intermediate host, which plays the role of a carrier (fleas, moths, mice, rats, cockroaches).

The main symptoms are: helminthiasis is not easy to determine, since the external manifestations of this ailment are quite blurred. When tapeworms infect rodents, acute or chronic diarrhea, loss of appetite, and general exhaustion are observed. Infection with nematodes is manifested by loss of appetite and weight loss, up to painful thinness.

Treatment: helminthiasis treatment is based on drug therapy, for invasion with tapeworms, Niclozamide is used in the calculation of 100 mg / kg of rodent mass, or Praziquantel is not more than 10 mg / kg of body weight. Nematodes are fought with piperazine citrate.

Eye diseases

Most often, the eyes of domestic hamsters suffer from ailments such as conjunctivitis and cataracts. Conjunctivitis is an acquired pathology that occurs due to the ingestion of various pollutants on the mucous membrane of the eyes with dust or due to an infectious lesion.

With untimely treatment, this ailment leads to the destruction of the eyeball

The main symptoms are: conjunctivitis can be recognized by the characteristic swelling and redness of the eye, which are accompanied by the release of purulent fluids from it. At the same time, the eye of the animal is often squinted or completely closed.

Treatment: conjunctivitis of various etiologies is treated with the drug Albucid, it is instilled directly into the rodent eye 3-4 times a day for 1-2 drops. Cataract is treated surgically, for this clouded lens is completely removed along with the eyeball.

Cataract happens congenital and acquired, congenital arises as a result of genetic abnormalities, acquired as a complication of eye injuries or diabetes.

The main symptoms are: cataracts appear as a white speck on the lens of the eye. This pathology can also be identified by related signs, due to a decrease in the effectiveness of the visual organ, the rodent often moves slowly, uncertainly and reluctantly.

Treatment: cataract is treated surgically, for this clouded lens is completely removed along with the eyeball.

Respiratory diseases

Most often, domestic hamsters suffer from diseases of the respiratory system. The most common among them is pneumonia. It develops thanks to a variety of strains of pneumococci, due to a sharp decrease in immunity.

The disease requires immediate treatment, otherwise pneumonia can be fatal.

Main symptoms: against the background of a sharp deterioration in the total activity of the rodent, there is a lack of appetite, cough, hoarse breathing, nasal discharge, mucous membranes become bluish. Conjunctivitis often develops against the backdrop of an ailment, with all the attendant symptoms.

Treatment: the fight against the disease is carried out using various antibiotics of a wide spectrum of action, vitamin C, sulfa drugs, glucose are used as auxiliary agents in general therapy.

A variety of ODS infections are also found in hamsters. Most often, diseases of this group occur during periods of sharp drops in temperature.

The main cause of the disease is a variety of pathogenic strains of viruses that are transmitted by humans or other animals.

Also, the disease can develop against a background of severe hypothermia or excessive stress.

The main symptoms are: catarrhal infections are most often manifested by lacrimation, coughing, hamster sneezing, shortness of breath, accompanied by wheezing, as well as rhinitis. With untimely treatment, general malaise, drowsiness, and loss of appetite develop.

Treatment: in mild forms of the disease, the rodent is placed in a warm place (near the battery, etc.), at this stage the treatment is carried out with the help of light aqueous solutions of honey and milk, which is replaced with drinking water. In severe forms, the use of a wide range of antibiotic drugs, as well as vitamin C, as an excipient, is indicated.

The most dangerous disease of the respiratory system in hamsters is lymphocytic choriomeningitis.

An ailment is a viral infection that is caused by an arenovirus. The main carriers of infection are mice and rats.

The disease causes inflammation of the meninges of the animal, and in some cases, even brain matter

The main symptoms are: with damage to the body, the pet has an increase in body temperature, fever, respiratory failure, lethargy and weakness.

Treatment:Today, effective therapy against lymphocytic choriomeningitis in domestic rodents does not exist, therefore veterinarians recommend euthanizing sick pets.


Often, constipation in rodents is the result of an improper diet. They arise as a result of the predominance of dry feed in the hamster's diet with a lack of drinking water. This leads to blockage of the intestine, as a result of which the animal has a violation of the excretory system and intoxication of the body with stagnant secretions.

The main symptoms are: constipation can be detected by the structure and amount of feces, it becomes harder than in healthy individuals, and its amount is significantly reduced. Often, constipation is accompanied by pain, so the animal loses activity, and its movements throughout the cell occur in a shrunken state. Related symptoms of constipation include loss of appetite and uncharacteristic wetting of the anus.

Treatment: to eliminate pathology, the diet is adjusted, for this, dry food is almost completely changed to plant food (boiled carrots, beets, etc.). To improve bowel movements, the animal is given 1 g of castor oil. In the case of serious complications, medication with laxatives is indicated.


Diarrhea in hamsters can develop due to a number of reasons, but most often its cause is a sharp change in diet. These include an increase in the amount of plant foods, as well as raw foods.

In most cases, the disease is not life threatening to the rodent, but it leads to depletion and dehydration, which can lead to the development of other digestive disorders.

The main symptoms are:diarrhea is manifested by frequent and watery discharge, loss of appetite, irritability, and exhaustion of the body.

Treatment: often pathology can be eliminated with the help of many means, the most often used 5% Baytril solution, which is added to drinking water with the calculation of 0.5 ml / 100 ml of water. You can also use decoctions of chamomile, oak and St. John's wort, which completely replace drinking water. At the same time, all juicy as well as raw foods are removed from the diet to the maximum.

Wet tail

Wet tail (colibacillosis) - This is a species-specific disease that affects almost all domestic hamsters. It has an infectious nature and is caused by the world famous bacteria. Escherichia coli (E. coli).

The microorganism is a typical representative of the intestinal microflora of mammals and is found everywhere. However, under certain conditions, the bacterium begins to multiply rapidly, which leads to damage to the digestive system.

The main symptoms are: profuse diarrhea is characteristic of colibacillosis, but this symptom develops only with clear signs of damage to the body. The primary symptoms of the disease include loss of appetite, lethargy, anxiety, and weight loss.

Treatment: general therapy to eliminate the ailment is to take antibiotics, for this purpose a 2.5% solution of Baytril is used. The drug is administered subcutaneously, 1 time per day for 1-2 weeks, 0.4 ml (10 mg) per 1 kg of rodent body weight. In especially severe cases, the dosage is increased to 2 doses per day. In addition, the rodent is shown to restore water balance, as well as taking probiotics to restore healthy microflora.

Rectal prolapse

The disease is a violation of the anatomical structure of the digestive system, as a result of which the prolapse of the intestine from the anus is observed. Pathology does not occur spontaneously and is often a complication of such disorders in the work of the digestive tract, such as diarrhea and constipation.

The ailment is often not dangerous for the rodent, but it sharply reduces the quality of its life.

The main symptoms are: pathology can be identified by the characteristic edge of the intestine falling out of the anus.

Treatment: the treatment of the disease is carried out by returning the rectum to its initial position, but in case of damage, the complete removal of the injured areas is indicated. In addition, the elimination of the main causes of prolapse of the rectum, which includes constipation and diarrhea, is also shown.


There are several reasons for the appearance of abscesses on the skin of hamsters, but often the pathology manifests itself as a result of an infectious lesion of damaged skin areas. Usually abscesses occur on the legs of the animal, since this area is most often susceptible to damage.

The main symptoms are: it is quite simple to recognize the abscess, the affected area becomes inflamed, swelling and redness of the skin appear. In some cases, the abscess is accompanied by the release of pus through a small wound. With untimely treatment, the hamster develops general weakness, malaise and refusal to eat.

Treatment: to eliminate the pathology, it is necessary to remove the pus using surgical instruments, then treat the wounds with peroxide (3% solution) and iodine, and then apply a patch with Levomekol. Periodically, the wound requires washing with a 3% peroxide solution at least 1 time per day until complete healing. If the abscess is not immediately detected and the animal feels bad, its activity is reduced, the first signs of sepsis are observed, in which case the use of antibiotic agents is indicated. The most popular among them is a 2.5% solution of Baytril, it is administered subcutaneously with a calculation of 10 mg / kg of animal body weight.


Dehydration found in many hamsters, often this process is a consequence of diarrhea of ​​various etiologies or arises as a result of a lack of drinking water.

Dehydration with profuse diarrhea is especially dangerous, in which case water is practically not absorbed by the body, since it passes through the digestive system in transit.

The main symptoms are: dehydration is manifested by a general weakening of the body, weight loss, slow and difficult breathing. The elasticity of the skin is also violated.

Treatment: to eliminate the pathology, drug treatment with Ringer's Lactate preparation or normal saline (0.9% sodium chloride solution) is indicated. The medicine is administered by subcutaneous injection at the rate of 40 ml / kg of animal weight, 2-3 times a day until the signs of pathology are completely eliminated. To increase the effectiveness of therapy, injections of 5% glucose solution, ascorbic acid, as well as Katozal are used.

Baldness (alopecia)

Alopecia or baldness - This is a pathological process of hair loss, which leads to a partial or complete loss of hairline by a rodent. The reasons for this disease are many, but in most cases it is a consequence of metabolic disorders, or occurs after prolonged stress.

The main symptoms are: alopecia is manifested by complete baldness of the hamster, or loss of hair in certain areas, while the skin remains smooth and clean.

Treatment: general therapy for eliminating alopecia is to improve the diet of the rodent, as well as the use of fortifying vitamins, in particular A and E. If alopecia is a consequence of emotional stress, the animal must be completely protected from all stress factors.


Obesity hamsters often develop due to poor diet, as well as a sedentary lifestyle. But in some cases, this disorder is the result of more serious illnesses (diabetes, metabolic disorders, etc.).

The pathology itself does not cause instant complications, but over time, the hamster can develop diseases of the cardiovascular system.

The main symptoms are: the symptoms of this disorder are quite simple, the animal is rapidly increasing in size, while its mobility and energy are reduced at times, shortness of breath develops.

Treatment: to eliminate, they carry out a comprehensive improvement in the nutrition of the animal, all excessively high-calorie foods that are replaced with fresh or boiled vegetables are excluded from its diet. To speed up the process of losing weight, a hamster should definitely buy a sports wheel or a walking ball.


All kinds of tumors are a fairly common pathology among small rodents, but most often individuals of this age are affected by this ailment. Today, the causes of this disease are not fully known, but most often they develop due to the development of abscesses and inflammation of the lymph nodes.

Tumors in hamsters, as in humans, are of two types: benign and malignant.

The main symptoms are: tumors appear as peculiar growths of a rounded shape. They are not inflamed, have a dense structure. Over time, education can increase significantly in size. In the case of a benign tumor, the pathology does not cause pain. Malignant tumors are often accompanied by severe pain, and also cause depletion in the animal and reduce its activity

Treatment: in the case of a benign formation, the pathology is eliminated by surgical intervention, if the tumor grows slowly and does not threaten the life of the pet, it is not removed. Malignant tumors do not respond to treatment; when diagnosing such a pathology, the animal is recommended to be euthanized.

Hypothermia (cold)

Like humans, hamsters also suffer from colds. These animals are quite susceptible to sharp drops in temperature and moisture, so even the smallest draft can cause a cold. The disease itself is not dangerous, but with untimely treatment, it can develop into pneumonia.

The main symptoms are: most often with a cold, the hamster has a decrease in activity and appetite, sneezing, noisy breathing, wheezing. Also, with colds, conjunctivitis can also develop.

Treatment: often a cold is treated quite quickly, for this the rodent needs to be given a warm solution of honey with milk. To improve the effect, the pet should be placed in the warmest place in the room, and also be provided with additional sources of vitamin C. In case of a protracted cold, it is necessary to carry out general therapy with broad-spectrum antibiotic drugs.


Domestic hamsters are active and curious animals, so they often have fractures. Often the person responsible for the fracture is. Due to negligence, quite a few owners injure a pet with their own hands, especially if small children are involved in caring for the animal.

But the hamster can be injured himself, because of his natural interest in everything around him.

The main symptoms are: a fracture can be recognized by the characteristic swelling of the affected area of ​​the body. With fractures of the legs, a shift in their natural position may be observed, which is accompanied by complete limb dysfunction. It is not uncommon for injuries to cause a pet to step on its foot, while moving with a characteristic limp. With open fractures, a bleeding wound is observed.

Treatment: due to the small size of the animal, fractures are not treatable, therefore, the body is restored naturally. The main help to the pet is to eliminate all the causes that may cause repeated trauma until the moment of full recovery. But with open fractures, it is necessary to correct the limb at the veterinarian, as well as daily lubricate the wound with all kinds of antiseptics.


Rickets, as a rule, in rodents is seasonal. The ailment appears in the winter, as a result of a lack of vitamin D (calciferol), but it can also occur with hypovitaminosis.

Often, rickets is a consequence of a malfunction of the endocrine system, in which case it acts as an additional symptom of a general disease. Rickets leads to a variety of bone tissue pathologies that favorably affect the further development of severe lesions of the rodent's musculoskeletal system.

Main symptoms: rickets can be recognized by the characteristic sagging of the hamster's spine, thickening of bones in the limbs and joints. Not infrequently, the disease disrupts the digestive system, in which case rickets is accompanied by a general digestive upset and diarrhea.

Treatment: treatment of rickets consists in replenishing the pet’s body with vitamin D. Specialized vitamin complexes are used for these purposes, as well as a special diet. It consists in enriching the diet with salts of phosphorus and potassium. In addition, to improve the effect of the diet, the rodent is shown any biologically active preparations with a high content of calciferol.


Cystitis is an inflammatory disease of the bladder. Most often, it arises as a result of a sharp overcooling of a rodent, both in the cold periods of the year and in the summer. Cystitis can also have an infectious nature, in which case the disease is caused by the natural microflora of the bladder and its ducts.

The disease is a rather dangerous pathology, since untimely treatment can lead to serious inflammatory lesions of the entire excretory system.

The main symptoms are: it’s not difficult to notice cystitis in the hamster, with this disease the animal has anxiety, constant urination, often with bloody discharge, as well as an increased need for drinking water. Due to constant contact with urine, small bald patches may appear on the hind limbs of the rodent.

Treatment: they fight the disease by subcutaneous injections of the drug Chloramphenicol with the calculation of 50 mg / kg of the rodent's weight, as well as with Buscopan or Sulfanilamide. The general course of treatment is no more than 6 days.


Scabies is a parasitic disease caused by the scabies mite. Parasitizing on the upper skin, the insect causes severe itching. In attempts to get rid of it, the animal combs the surface of the body, which leads to the formation of wounds on his body, which often end in an abscess.

The itch mite can also parasitize in humans, so when the signs of the disease are first detected, the parasite should be immediately eliminated.

The main symptoms are: it is almost impossible to see the scabies mite with the naked eye, therefore its development can be suspected only by the characteristic combing by the pet of its own body.

Treatment: Parasitized areas are treated with a 3% solution of SK-9 and Sulfur Ointment. For treatment, a mixture of 1% Chlorophos solution and 1% solution of D-33 is also used. Processing is carried out once and repeated after 6-7 days.


Enteritis is an infectious disease of the digestive system. An illness is caused due to joint infection of the digestive organs with bacteria Echerichia coli and Campylobacter phetus.

The main cause of enteritis is an unbalanced diet, namely an insufficient amount of hay and other roughage in the diet.

This ailment is a fairly serious defeat of the body, since with untimely treatment it causes the death of a rodent.

The main symptoms are: the first sign of enteritis is severe diarrhea, which after some time develops into bloating, the animal refuses food, loses activity.

Treatment: enteritis is quite difficult to treat, in most cases, the main therapy is the use of Neomycin and Netracycline, but still the infection in many cases leads to death.

The most common diseases of hamsters

Cold. The first symptoms are discharge from the nose, sneezing, tearing of the eyes, apathy, weight loss, later wheezing in the lungs, difficulty breathing may be added. The hamster should be placed in a warm room, away from drafts, given warm water, milk with honey, fruits, immunomodulators. If you do not start a cold, in a couple of days it will pass by itself, otherwise, it may turn into pneumonia or bronchitis, and the animal will have to inject a course of antibiotics.

Abscesses and abscesses. There are several reasons for the appearance of abscesses: mechanical injuries, infection, reduced immunity. Basically, local treatment is prescribed: healing ointments (levomekol, zinc), a course of immunomodulators. If this is a purulent abscess, it is opened, after which 2 times a day is treated with hydrogen peroxide, chlorhexidine, an ointment is applied. If there is no positive trend in treatment, antibiotics may be prescribed.

Tooth problems. Like many rodents, hamsters quickly grow teeth. So that the pet does not feel discomfort, you need to give him solid feed, about which he will grind the incisors. However, if there is already a problem, it will remind of itself: the first signs are increased salivation, loose closing of the jaws, refusal to eat. Only the veterinarian can grind the incisors and remove sharp hooks on the teeth with a drill or side cutter.

Dermatophytosis. Often, the disease manifests itself when the animal has weakened immunity. Hair falls out, exfoliating flakes, sores, scabs appear on the skin. If you start the disease, a secondary infection will begin. The causative agent is a special group of fungi, accompanied by pathogenic bacteria. Mandatory treatment with antiseptic ointments like Imaveral, Zomekol, Fungin, you can use the antifungal shampoo Fuciderm, treat wounds with chlorhexidine or miramistin. The animal is given a course of immunomodulators such as Venom, in the presence of infection - antibiotics.

Diabetes. This is mainly a genetic vulnerability, more characteristic of Campbell's hamsters. Symptoms - increased thirst, frequent urination, the appearance of non-healing wounds, weight gain, drowsiness. There is no universal cure for diabetes: first of all, a diet is prescribed, sugar and most carbohydrates are excluded. Since there are few professional mixtures for hamsters with diabetes, it is better to make them yourself: seeds of flax, millet, oats, hemp can become the basis of the mixture. As an additional therapy, the veterinarian may prescribe homeopathy (for example, fenugreek hay). Individually prescribed medications with insulin - Glipizid, Glucotrol, Melisid, Mindiab, Minodiab, Glibenez and others.

Eczema. The first signs of eczema are dry hair, exfoliating scales, wounds, growth retardation may be observed in young individuals. Often the cause of eczema is stress, a change of scenery, an allergic reaction. First of all, you need to change the litter - some hamsters are allergic to shavings and sawdust, they are replaced by hay. The affected areas are lubricated with Fuciderm, Zoomekol, Imaveral and other ointments twice a day. Eczema is often confused with parasitic infection (ticks, lice), it is better to take tests and show the animal to the veterinarian, since the problem associated with parasites is treated with other means.

Colibacillosis. This disease is also called “wet tail”, but this is not just an upset gastrointestinal tract, but a disease of a bacterial nature. The first symptoms are liquid feces, the coat around the anus is moist, the animal behaves uneasily, is hunched over, tries to shrink into a lump. The hamster is fed a solution of electrolytes and isolated as quickly as possible from the rest, it is necessary to show all animals to the veterinarian. Tetracycline, baytril are drunk with drinking water, chloramphenicol and similar drugs are injected subcutaneously. During the day, you can give animals only hay, decoctions of chamomile, St. John's wort. The prognosis for colibacillosis is not the most favorable, it is important not to miss the disease in the initial stages and start treatment on time.

Aujeszky's disease. Also, this disease is called "false rabies." The causative agent is a virus that affects the nervous system of the animal. Only after 2-3 weeks do the first symptoms appear: itchy skin, restless and agitated behavior. For treatment, gammaglobulin and hyperimmune serums are used. If you start the disease, the hamster will begin to paralyze the swallowing muscles, which leads to death.

Cystitis. It manifests itself by frequent urination, the hamster behaves uneasily, beeps, tries to find a comfortable position. For treatment, sulfonamides, buscopan are used, the course is at least 6 days. If the symptoms reappear, a thorough examination is necessary: ​​similar manifestations occur with stones in the bladder - they are removed only by surgical means.

Lymphocytic choriomeningitis. One of the few “hamster” diseases that are dangerous for humans can be almost asymptomatic, the main manifestations are sharp weight loss, decreased activity, it happens that hamsters are infected already at birth, the virus remains active for 12 weeks, so we strongly recommend not to buy hamsters younger than 3 months. The disease is especially dangerous for pregnant women, it can cause pathologies in the fetus. If a virus was found in the hamster, the animal is treated with ribavirin and its derivatives, all objects in the cage are thoroughly disinfected.

  • hamsters love to eat and if they suddenly refuse to feed, beware,
  • anxiety becomes increased thirst,
  • worth worrying if increased salivation,
  • Wet hair on the back or traces of feces are also disturbing,

  • the hair of a sick hamster grows dull and begins to fall out,
  • unnatural swelling is visible on the body,
  • the animal becomes inactive and lies almost all the time,

  • the bag is sometimes clogged, the reason for this is not only small grains, but pieces of paper or cotton wool, especially when they dry in a bag, the help of a veterinarian is necessary to clean them, otherwise inflammation will begin,
  • it happens that a hamster, trying to free a clogged bag, literally twists it, then the veterinarian’s help is urgently needed - the bag is returned to its place and slightly hemmed, the sutures are removed after 2 weeks,
  • if the sac inflames severely, it is removed surgically,
  • sometimes the sacs are affected by a tumor, this is called neoplasia, - tumors of this kind are also removed.

At home, a hamster can exist without bags, because he does not need to stock up on food. But in nature, without these organs, a hamster usually dies of hunger in the winter.

Dental problems

It happens that the hamster often bites the metal rods of the cage and breaks the incisors. It is not necessary to worry much about this, they will grow back naturally.


In rodents, cataracts are even more common than, for example, in dogs or cats. Unfortunately, it is very difficult to notice this disease at an early stage due to the small size of the eyes in these animals.

ATTENTION! When a cataract develops, it may not bother the rodent at all. But with the decay of a mature cataract, inflammation inevitably passes to the eye, and the animal dies.

Removing cataracts in small rodents is technically possible using the elements of microsurgery. But even abroad, they are practically not fulfilled due to the high cost. Veterinary care in such cases consists in the complete removal of the eye.


This is an acute infectious disease that usually ends in the death of an animal. Young animals under 24 weeks old are usually exposed to it.. The disease has 3 forms:

  • acute - the disease develops very quickly: the animal rises sharply and diarrhea with blood opens, hamsters with such symptoms usually die within a week,
  • subacute - death can occur within 2 weeks,
  • chronic - the incubation period lasts up to 1 month.

  • often the animal saliva liberates abundantly,
  • vomiting or diarrhea begins,
  • in a state close to critical, convulsions can occur, followed by paralysis.

The disease is caused by coccidia - the simplest parasites. These microorganisms can live in the intestines of an animal without causing complications. However, they begin to multiply rapidly on condition of poor feeding or dampness.

The disease causes diarrhea, bloating, lethargy. Treatment is possible with antibiotics with changing conditions. If you do not engage in the treatment of pathology, the animal may die.


Under natural conditions, the hamster lives on the plain, therefore the concept of height is not developed for him. He can fall off the table, off the couch, just fall out of the cage. The consequence may be a fracture of the limb.

In this case contact your veterinarian and apply a fixative bandage. In severe cases, amputation of the limb may follow, but this is not fatal.

It is not difficult to stop this condition; it is enough to purchase food with vitamin supplements in the store. You can use vitamins for people, for example, compliit.

In the acute form of the disease, the animal usually dies in a few days, it is not amenable to veterinary treatment.


Rarely, in rodents, fleas, lice, or lice eaters can be found on the body. You can determine their presence when examining the skin, slightly spreading the hair of the animal. The hamster often itches and is anxious. It is easy to get rid of such uninvited guests with the help of special shampoos.

It is easy to get rid of worms, using the appropriate drugs. Just do not delay it. Helminths can quickly cause severe intoxication of the rodent and its subsequent death.

  • vitamin deficiency
  • fungus
  • the presence of skin mites,
  • As already noted, lichen can cause alopecia.

  • the hamster becomes lethargic
  • sometimes he trembles
  • coughing and wheezing occur
  • the animal is losing weight fast.
