If you notice sticky and wet droppings take your hamster to the vet immediately to see if it is diarrhea or a wet tail.

Difference between diarrhea and wet tail

Although diarrhea and wet tail have similar symptoms, they are different.

Diarrhea is watery feces that can be caused by several reasons such as food, stress, etc., but if it is promptly treated by a veterinarian, there is a good chance that the hamsters will be cured.

A wet tail is an intestinal disease caused by harmful bacteria. When hamsters have a wet tail they die in 90% of all cases.

Why do hamsters have diarrhea?

As we said at the beginning, diarrhea in hamsters can occur for several reasons, such as food, stress, bacterial infections, etc.

So let’s find out in detail about all these reasons and how they cause diarrhea in hamsters.


When hamsters eat too many vegetables and fruits, diarrhea occurs, it is especially risky when they eat a lot of lettuce.

Lettuce, like other vegetables that have a lot of water in their composition, causes watery diarrhea.

Also, when they eat food that has a lot of fiber, they get diarrhea, such food is:

  • apples
  • kiwi
  • bananas
  • spinach
  • broccoli

To overcome diarrhea, hamsters should eat solid food.


Worms are not often the cause of diarrhea, but sometimes they can be the cause of diarrhea in our furry friends.

The worms feed in the large intestine of hamsters and are transmitted through their eggs.

They go from the anus of an infected animal, to then contaminate bedding, food, and water and enter their body through the hamster.

Wet tail

A wet tail causes diarrhea because it causes inflammation of the small intestine. When hamsters have a wet tail, they die in 90% of all cases.

Wet tail occurs when the intestinal bacteria Lawsonia intracellularis and Campylobacter grow very quickly in the hamster’s body.

A wet tail appears due to the following factors:

  1. poor diet
  2. poor cage conditions
  3. change of environment and home
  4. inflammation of the GI tract

Antibiotics can cause diarrhea

Antibiotics are used to treat hamsters, but they can also cause intestinal problems in your pet.

Antibiotics such as ampicillin and penicillin kill bacteria in the digestive tract, which causes harmful bacteria to grow.

Then diarrhea appears, which can kill the hamster in 3-10 days, if not treated in time.

Apart from diarrhea, signs of dehydration, a decrease in appetite, and a decrease in body temperature also appear.

If the hamsters have problems when using antibiotics, it is necessary to change them or to treat the hamsters in another way.what to do when your hamster has diarrhea


Stress causes diarrhea in hamsters, and they are very timid and get stressed very easily.

Hamsters get stressed in the following situations:

  • poor diet
  • poor hygiene
  • a lot of noise
  • too much light
  • other pets near them

When hamsters are stressed, harmful bacteria grow too quickly, and eventually, diarrhea occurs.

Tyzzer’s Disease

Tyzzer’s Disease occurs as a result of the bacterium Clostridium piliforme when hamsters eat contaminated feces.

This disease has very similar symptoms to wet tail and mostly affects younger hamsters and those that are under stress.

When hamsters have Tyzzer’s Disease they need to use antibiotics prescribed by a veterinarian to recover.

While hamsters have this disease you should pay very close attention to cleaning the cage and hygiene as much as you can.

Protozoal infections

Protozoal infections. are the reason why hamsters can get diarrhea.

Most often Protozoa are found in the digestive tract of hamsters but do not cause symptoms of the disease.

Again, young hamsters and those who are under stress are most exposed to the occurrence of diarrhea due to protozoal infections.

Veterinarians can help as they can determine if this is an infection by testing the hamster’s droppings. Fortunately, protozoal infections are easier to treat, which is most important for our furry friends.


Tapeworms are more common in our furry friends than in other rodents and are usually transmitted through food and water.

Diarrhea is a side effect of tapeworms, although sometimes such problems do not occur due to tapeworms.

When the tapeworm causes diarrhea, it is manifested first by:

  • intestinal blockage
  • inflammation
  • lymph gland infections

How to treat diarrhea in hamsters?

Less stress

  • no other pets around the hamsters

Better conditions

Hamsters need to always have excellent hygienic conditions to reduce the chances of diarrhea.

If his cage is not clean enough, and there are too many bacteria, dirty bedding, and dirty food, then diarrhea can easily occur.

Therefore, we should regularly clean the cage and change the bedding once every two weeks.

Deep cleaning of the cage should be done once a month, especially to clean the places where the hamsters urinate and poop.
