When properly cared for, hamsters rarely get sick. However, you will need to obtain professional help whenever your pet needs it. It is possible to treat a sick hamster if the illness is detected in time.
Finding a Veterinarian
If you don't already have a veterinarian, you'll need to find one and establish a relationship so you have someone to call in case of emergency illness or injury. To find a veterinarian who treats hamsters, look up an exotic animal veterinarian in the phone book or ask your hamster-owning friends for a referral to their veterinarian.
Establishing a Clean Bill of Health and a Firm Foundation
When you first adopt your hamster, examine her thoroughly. Ask the seller if he or she has a pet guarantee. Without this guarantee you will be unable to return your pet should you discover a health problem when you bring your new hamster home.
Housing and Hamster Reproduction
Most hamsters prefer to live alone so it is best to keep your pets in separate cages, regardless of gender, to prevent fighting. Never house adult hamsters together.
Good animal husbandry should prevent most hamster illnesses, so find out as much as you can about hamster hygiene and how to keep your pet healthy. Also, on a weekly basis, check your hamster for any signs of illness such as diarrhea, loss of appetite, lethargy, mites or overgrown teeth. If you notice any of these, consult your exotic animal veterinarian promptly.
