What is the yellow stuff coming out of your hamster?

If your hamster is excreting yellow discharge from its nose or eyes, it is important to take it to a veterinarian as soon as possible, as it could be a sign of a serious health problem.

Some of the possible causes of yellow discharge from a hamster's nose or eyes include:

Upper respiratory infection: This is a common respiratory illness in hamsters, caused by bacteria or viruses. Symptoms include sneezing, nasal discharge, and eye irritation.

Pneumonia: This is a serious infection of the lungs, which can be caused by bacteria or viruses. Symptoms include difficulty breathing, rapid breathing, and weight loss.

Allergies: Some hamsters may develop allergies to certain substances in their environment, such as dust, pollen, or certain foods. Symptoms of an allergic reaction can include sneezing, eye discharge, and skin irritation.

Eye injury: A hamster's eye can be injured by scratches or cuts from sharp objects, or by chemicals or other irritants. Symptoms of an eye injury include squinting, eye discharge, and rubbing at the eye.

Dental problems: Some dental problems, such as overgrown teeth or misaligned teeth, can cause a hamster's eyes to water excessively. Symptoms of dental problems include difficulty eating, weight loss, and excessive salivation.

It is important to take your hamster to a veterinarian as soon as possible if you notice any signs of illness, including yellow discharge from the nose or eyes. The veterinarian will be able to diagnose the cause of the problem and prescribe appropriate treatment.
