If you notice a hamster’s bottom is wet, then there is a high chance that hamster is suffering from a bacterial disease known as Proliferative Ileitis, or “wet tail”. Wet tail in hamsters is a serious condition caused by an infection in the intestinal tract, often affecting hamsters less than seven weeks old. Outwardly, this intestinal condition manifests as a soiled or wet appearance around the hamster’s tail. The infection is caused by a strain of bacteria known as lawsonia intracellularis, and is contracted when the animal has consumed food or water that has come into contact with infected fecal matter.
Though all breeds can suffer from wet tail, it is most often found in the long haired teddy bear hamster, a type of Syrian hamster. Adolescent hamsters are most susceptible to contracting this disease, though adult hamsters can also be affected. Hamsters that were raised in cramped, unsanitary conditions tend to suffer from wet tail.
A newly purchased hamster that is already suffering from wet tail will show numerous symptoms. If you notice your hamster has wet stool, low energy levels, lack of desire to eat or groom himself, then that is a warning sign to see a vet. In extreme situations, there may be blood or mucus in the hamster’s stool.
Because this bacterial disease is so serious, even providing medical assistance at the earliest sign may still not be enough to save them. Treatment is usually as follows: a veterinarian will prescribe antibiotics as well as a solution to replenish depleted fluids. The vet will instruct you to keep the affected pet separate from other hamsters in a clean, dry, and quiet location to recover. The affected hamster’s cage will need to be thoroughly cleaned and disinfected.
Why is it that a young hamster affected by wet tail has such a low chance for survival? Scientists believe that it is a result of a genetic defect which compromises their immune system, making them vulnerable to all kinds of disease. The actual cause of death is dehydration due to all of the fluids they lose from their wet stool.
As a pet owner, it is your responsibility to take preventative measures so that your pet hamster will not develop wet tail. You must clean their dishes and feeding tubes daily. If you notice droppings around food or water containers, clean it up immediately. Once a week, remove all the bedding in the hamster cage and put in fresh bedding. Do not suddenly change their diet as well, since this can stress your hamster out which can lead to illness.
