Answer Wet tail is caused by a bacterial infection of the intestine and can often be fatal. Symptoms include diarrhea accompanied by a strong, unpleasant smell. The hamster often walks hunched up, is weak and lethargic and may squeal in pain.

If your hamster is showing signs of this disease, it is very important to take him to a veterinarian immediately. Treatment includes antibiotics as well as electrolyte and fluid replacement. Some hamsters that survive the initial infection will later experience intestinal or rectal problems.

An increasing number of veterinarians treat small pocket pets like hamsters. Information on treating the diseases common to these pets is becoming more sophisticated all the time. The veterinary profession will continue to increase its knowledge of these pets' diseases as it has for cats, dogs, birds and reptiles.
