Mice can develop digestive issues if fed an improper diet. Too many rich foods, or an excess of green vegetables and fruit can cause diarrhea. Antibiotics given to treat an infection somewhere in the mouse’s body can also cause diarrhea. Sometimes, a bacterial infection in the intestines can result in diarrhea.
If your small pet has diarrhea and you feed it a lot of greens and/or fruit, cut these out of its diet completely for a few days to see if the diarrhea subsides. If it does, add the foods slowly back into its diet, but keep them to a minimum. If the diarrhea persists, take your mouse to a veterinarian for a diagnosis.
Diarrhea that follows treatment with antibiotics can often be treated by giving probiotics. Ask your veterinarian to recommend a probiotic paste or powder you can administer to your small pet.
Constipation is another problem that can plague mice. The most common cause of this condition is intestinal parasites in the form of pinworms or tapeworms. Mice infected with these parasites often groom their rectal area excessively, lose weight and become lethargic. If your mouse shows these symptoms, take it to a veterinarian immediately for deworming.
To prevent digestive problems, feed your mouse a balanced diet of mouse or hamster pellets along with a small amount of fresh foods each day. Be sure to clean out its water bottle and bowl every day as well to cut down on bacteria, build up. Talk to your veterinarian about deworming your mouse to prevent parasitic infection.
