Hamster Wet Tail

Look our for this disease!

Hamster Wet Tail is actually a disease that can be found in a variety of rodents, but most commonly found affecting hamsters. This disease can cause death in a day or two. It is also contagious to other rodents.

*Disclaimer: I am not medically trained nor does this site present itself so. I offer facts, knowledge of options, and my experiences to help you recognize danger. When your hamster displays symptomatic behaviors, always seek a licensed vet's opinion. Save up a little stash for those times.


Wet tail is a type of bacteria in the small intestines that causes the body to deteroriate rapidly. Your hamster may catch this disease by ingesting fecal matter and being stressed.

Notice that stress is a important factor. This makes sense because healthy wild hamsters routinely ingest their own feces without any issues. But when a hamster is stressed and weakened, they may become susceptible.


A hamster may become stressed for a variety of reasons. Here are some common ones:
  • Cage cleaning may upset a hamster because it loses all the placement and goodies it thinks of has his or her home.
  • Dirty habitat can also stress a hamster. A suggestion would be to clean out the cage once a week but keep one handful of old bedding to comfort your hamster.
  • Too many hamsters in one habitat. Syrian hamsters are solitary animals and also the most likely to catch Wet Tail. Could there be a correlation?
  • Pups are more likely to get Wet Tail. Pups need to stay with their mothers and siblings until weaned.

Recognize Hamster Wet Tail

Wet Tail can kill in a day or two and can be passed on to other rodents. Your best bet to save your hamster is to take it to a vet right away. Once you notice these signs, don't wait:
  • Wetness around the rear end and lower tummy area.
  • Your hamster seems lifeless, hunched, not interested in food.
  • Diarrhea.
  • Smelly.


A vet will issue a drug that hopefully will treat your hamster in time. Hope this gives you some idea of what to do. If you're concerned about the price, call several vets and ask what they'll charge. Sometimes vets will reduce the price just to give the care your pet needs!
