Hamsters are popular pets favored by many. They belong to the rodent family and are friendly, gentle creatures that children love. They enjoy playing due to their small size, which ranges from about 5 to 33 cm in length, weighing less than half a kilogram. Hamsters have tails and come in various colors, including brown, white, yellow, red, and black. To ensure a hamster’s well-being, it is crucial to take good care of its health and prevent illnesses. Additionally, hamsters can transmit bacteria and infections to children under eight years old if they do not wash their hands after handling them.
Due to their small size, hamsters are vulnerable to numerous diseases, especially those caused by fungi and bacteria. Keeping their living environment clean is essential to minimize these risks. They can also suffer from digestive and respiratory diseases. Below are the most common diseases that affect hamsters and ways to prevent them، Here are the details from teketrek.
Common Diseases in Hamsters
Hamsters are highly sensitive animals and are prone to many illnesses, including respiratory, digestive, and skin diseases. Here are some of the most common conditions that affect hamsters:
Respiratory Infections
Hamsters can develop respiratory diseases such as colds, which manifest as frequent sneezing, difficulty breathing, and a wet nose. These conditions can be serious and require veterinary consultation for appropriate treatment. A mixture of clean water and honey can help alleviate severe colds, along with milk mixed with water and soft foods that are easy to chew.

Digestive Problems
Hamsters can suffer from digestive diseases like diarrhea, often caused by bacterial infections such as wet tail disease. They may also experience bloating due to constipation, infections, or gas buildup. In some cases, abdominal bloating may indicate the presence of serious tumors. To determine if bloating is a serious issue, avoid feeding gas-producing foods and ensure a proper diet. If the hamster’s condition does not improve, seek veterinary care immediately for medical examinations and treatment.
Skin Diseases
Due to their small size, hamsters are susceptible to skin diseases caused by bacteria and fungi, which can thrive in their fur. One common condition is mite infestations, leading to persistent itching, redness, and hair loss. Skin diseases can be treated by consulting a veterinarian for antifungal medications.
To prevent skin diseases, maintaining cleanliness in the hamster’s environment is crucial. Proper grooming and regular checks for parasites are necessary. If insects are found in the hamster’s habitat, this may indicate an infestation, requiring treatment with safe insecticides and topical medication for the hamster’s skin.
Causes of Diseases: What Does a Sick Hamster Look Like?
There are many reasons hamsters fall ill, and negligence by their owner is the primary cause. Poor hygiene in both the hamster and its environment can lead to skin diseases caused by mites. Exposure to extreme cold without proper temperature regulation increases the risk of respiratory infections. Additionally, feeding hamsters unhealthy foods high in fats and sugars contributes to obesity and digestive issues.
Treating a Sick Hamster
In most cases, treating a hamster is relatively simple, especially for minor illnesses. However, serious conditions such as tumors and wet tail disease are difficult to cure, often resulting in death. For respiratory infections like colds, treatment includes offering soft foods, honey-mixed water, and milk with bread. Ultimately, consulting a veterinarian for proper diagnosis and treatment is essential.
If you notice any of the above symptoms in your hamster, you should consult your nearest veterinarian. Treatment depends on the type of disease, and you must strictly adhere to the veterinarian’s instructions. Treatment may include the following:
- Medication: For example, antibiotics specifically designed to treat the infection your hamster has been diagnosed with.
- Dietary changes: This is to prevent diarrhea and other intestinal disorders, or to improve kidney health.
- Supportive care: This includes providing a quiet, comfortable environment away from noise and disturbance, as hamsters are very sensitive creatures.
