Understanding the signs, causes, and treatments of the most common diseases in these small animals allows for better management of their health, preventing serious complications and reducing their lifespan.
With a few simple gestures and preventive care, you can greatly reduce these risks. To keep you well-informed, here is an article that I will enrich over time, about common diseases in hamsters and how to avoid them.
1. Dietary and Digestive Problems
Digestive Diseases
The digestive diseases in hamsters include diarrhea, constipation, and gastrointestinal infections. These disorders can be caused by an inappropriate diet, overconsumption of juicy fruits and vegetables, or a sudden change in diet.
- Diarrhea: caused by excessive consumption of juicy foods or by a bacterial infection.
- Constipation: caused by insufficient fiber intake in the hamster’s diet.
- Gastrointestinal infections: contamination by internal parasites can lead to various digestive symptoms. Typically, these result from poor sanitary conditions or the consumption of contaminated food.
Indigestion
Indigestion is another common disorder that can be caused by an unbalanced diet, high in sugars or fats. Symptoms include lethargy, lack of appetite, and abdominal swelling. A balanced diet tailored to the specific nutritional needs of hamsters significantly reduces the risk of indigestion.
2. Abscesses
Hamsters may sometimes develop abscesses, which often appear as bumps on their bodies. These bumps can be small and therefore difficult to detect without a careful visual examination. Generally, an abscess forms following an untreated infection. If the abscess ruptures, you may see foul-smelling liquid escaping, which can be white, yellow, or greenish. Keep an eye out for these signs to intervene quickly and ensure your little companion’s health!
Treatment of Abscesses
The only way to treat an abscess in your hamster is to consult a veterinarian. They will incise and clean the abscess to eliminate the infection. In some cases, surgical intervention may be necessary to prevent the abscess from refilling with pus. Antibiotics are often prescribed to prevent a new infection.
Never attempt to pop the abscess yourself, as it could worsen the situation and lead to complications!
Preventing Abscesses
To prevent abscesses in your hamster, promptly treat any cut or scrape. Use a cotton ball with warm water to clean the wounds, and avoid human disinfectants that could irritate their delicate skin. For any injury, even minor, it is always best to consult a veterinarian. With these precautions, you can help keep your hamster healthy and prevent infections.
3. Dental Problems
Dental malocclusion is common among rodents, including hamsters. This problem arises when the upper and lower teeth do not align correctly, leading to excessive growth of the incisors. Symptoms include difficulty eating, excessive salivation, and weight loss.
- Treatment: regular trimming of the teeth by a veterinarian.
- Prevention: provide chewable materials for natural wear of the teeth.
4. Dehydration
A dehydrated hamster can show several concerning signs. It may become lethargic, have skin that takes time to return when pinched, and urinate less frequently. Dehydration is often linked to other health problems.
Other symptoms include sticky eyes and loss of appetite. If you notice these signs, it is crucial to consult a veterinarian quickly to ensure your little companion’s well-being.
What to Do if Your Hamster is Dehydrated?
It is crucial to detect dehydration early in your hamster. If you think your little companion is dehydrated, place them in a cooler environment and consult a veterinarian immediately. While waiting for the vet visit, you can try to give them water with a syringe. In cases of severe dehydration, hospitalization with fluid administration may be necessary. Acting quickly can make all the difference for your hamster’s health.
Preventing Dehydration
To prevent dehydration in your hamster, ensure they always have access to clean, fresh water. Avoid placing their cage in direct sunlight and regularly check that their water bottle is functioning properly. During hot months, keep a close eye on your hamster to prevent overheating. These small precautions can help keep your hamster hydrated and healthy.
5. Wet Tail Disease
Wet tail in hamsters is characterized by severe diarrhea, foul odor, loss of appetite, and lethargy. Affected hamsters may also have a hunched back and exhibit aggressive behaviors. If you notice these signs, consult a veterinarian quickly to obtain a proper diagnosis and treatment.
This disease can be caused by a bacterial infection, internal parasites, an inappropriate diet, or stress. Syrian hamsters are more likely to contract this disease than dwarf hamsters.
Treating Wet Tail Disease in Hamsters
If you notice symptoms of wet tail in your hamster, take them to the veterinarian immediately. Quick treatment is crucial to increase their chances of survival. The veterinarian will provide supportive care, including antibiotics.
Change your habits as needed, and maintain good hygiene in the cage, cleaning everything the hamster has touched to prevent the spread of the disease. Acting quickly and following the veterinarian’s recommendations can make a big difference in your hamster’s recovery.
How to Avoid Wet Tail Disease
To prevent wet tail disease in your hamster, ensure you provide high-quality care. Avoid stressing them by handling too often or frequently changing their environment. Keep their cage clean and provide them with a balanced diet.
6. Cancers and Tumors
Tumors in hamsters can develop anywhere on their bodies. They may be visible directly on their limbs or detected through imaging examinations for internal organs.
Early signs of tumors include palpable masses under the skin, weight loss, decreased appetite, and behavioral changes. Establishing a early diagnosis allows for determining if surgical intervention or medical treatment is needed.
Hamsters can develop tumors, sometimes cancerous, particularly on the skin and internal organs. Mammary tumors are especially common in older females.
Tumors
There are two types of tumors in hamsters:
- Benign tumors: these tumors are abnormal cell growths that do not spread to other parts of the body. Although not cancerous, they can cause problems if they become too large.
- Malignant tumors: unlike benign tumors, these tumors can spread throughout the body, causing metastasis. A common example is lymphoma, which affects the lymphatic system and can manifest as skin disease.
Treating Cancer in Hamsters
If you notice a suspicious mass on your hamster, have it examined by a veterinarian. Surgery is often recommended to remove tumors, whether benign or malignant. Hamsters may also benefit from chemotherapy, which is less expensive due to the small doses required.
For palliative care options and to improve your hamster’s quality of life, consulting with a veterinary oncologist is highly advisable.
Genetic predispositions can greatly influence the development of tumors and cancers in hamsters. Even though you cannot change their genes, it is super important to regularly check their little bodies for any new lumps or masses. If you see something strange, rush to the veterinarian. By staying vigilant, you can detect problems early and ensure better health for your little companion.
7. Respiratory Infections
Respiratory infections in hamsters can manifest through various symptoms. You may notice that your little companion has wheezing, sneezes, coughs, or has a nasal discharge. Loss of appetite is also common, and your hamster may appear lethargic and have difficulty breathing.
- The common cold often presents with sneezing, nasal discharge, and labored breathing. It mainly occurs due to sudden temperature changes, drafts, or prolonged exposure to moisture.
- Pneumonia in hamsters is a serious infection affecting the lungs. It can result from an untreated cold or immune suppression due to other factors. Symptoms include difficulty breathing, weight loss, and fever.
Treating a Respiratory Infection
If you notice symptoms of a respiratory infection in your hamster, take them quickly to the veterinarian. For an accurate diagnosis, the vet may recommend x-rays and blood tests. Intensive treatment, sometimes including oxygen therapy, may be necessary to help your little companion regain health.
How to Prevent These Infections?
To prevent respiratory infections in your hamster, maintain a clean, dust-free environment. Ensure that their cage is always clean and well-ventilated, and avoid types of bedding that produce a lot of dust. Provide them with nutritious food to strengthen their immune system. If you are sick, avoid handling your hamster, as some human infections can transmit to these small animals.
8. Neurological Diseases
Epilepsy
Some hamsters suffer from epilepsy, characterized by recurrent seizures. Causes include genetic predispositions, head trauma, and brain infections. Symptoms include seizures, muscle rigidity, and temporary loss of consciousness.
Vestibular Syndrome
Vestibular syndrome affects balance and movement coordination. It can be caused by inner ear infections or brain injuries. Notable signs include a head tilted to one side, circling, and frequent falls.
9. Heart Diseases
Signs of heart diseases in hamsters can be quite concerning. If your hamster shows lethargy, rapid breathing, or wheezing or gurgling sounds when breathing, they may have heart problems. Gums taking on a bluish tint and fainting are also symptoms to watch closely.
Treatment for Heart Diseases
Although heart diseases in hamsters cannot be cured, they can be managed with appropriate medical treatments. Your veterinarian will need to perform an echocardiogram and x-rays to diagnose the specific problem. Medications may be prescribed to help manage symptoms, even though the disease inevitably progresses.
Preventing Heart Diseases
To help prevent heart diseases in your hamster, avoid obesity by providing a balanced diet and encouraging regular exercise. These habits will contribute to strengthening their cardiovascular system. Good nutrition and regular exercise opportunities are essential to keep your little companion healthy.
10. Skin and Parasitic Conditions
Demodicosis
Among skin conditions, demodicosis is common in hamsters. This disease is caused by Demodex mites that infest hair follicles. Symptoms include hair loss, scabs, and red patches on the skin.
Cuts and Wounds
Cuts and scrapes can easily become infected in the presence of bacteria. Unattended injuries can quickly develop into pus-filled abscesses. Strict hygiene and the application of antiseptic solutions help prevent infection.
- Immediate care: clean the wound with saline solution.
- Prevention: maintain a clean cage and avoid sharp objects.
11. Kidney Diseases
Hamsters suffering from kidney diseases drink and urinate excessively. Other signs include blood in the urine, weight loss, swelling due to water retention, and hair loss.
Kidney diseases can be caused by a diet too high in protein, infections, exposure to toxins, chronic dehydration, cancer, and amyloidosis, a condition where a protein called amyloid accumulates in the kidneys.
Unfortunately, once symptoms appear, kidney function is often severely reduced. In some cases, surgical removal of a diseased kidney may be considered. However, if both kidneys are affected, the prognosis is generally poor.
