This is a highly contagious bacterial illness that causes severe diarrhea in a hamster and can, and often does, prove fatal.

It can start with a pale discharge from the anus, although the initial symptoms are lack, or loss of appetite. Decline can be rapid and you should contact your veterinarian immediately veterinary to begin as soon as possible. Stress is an important factor in the cause of wet tail. Any sudden changes in diet, habitat overcrowding, extreme temperatures and unsanitary living conditions could be a causal
factor.

The can disease spreads rapidly, the strictest hygiene with thorough disinfecting of the cage and burning of bedding is imperative, especially if more than one hamster is kept, or if the case is to be re-used.
