What does wet tail in a hamster look like?

Wet tail in hamsters shows mainly as damp fur at the tail, dull eyes and frequent diarrhea. It relates to the living environment and may be caused by gastroenteritis, a cold or stress. It is common in hamsters around 3 to 6 weeks old, is somewhat contagious, and severe cases may die within 2 days, so owners should take the hamster to a vet promptly.

If a vet is unavailable, clean the cage, wipe the wet tail with tissue, stop feeding temporarily and give glucose for energy, then probiotics to regulate the gut.
