Colitis in Cats

How do I know if my cat has colitis?
Colitis is an inflammation of the colon, also known as the large intestine. Colitis can be acute, beginning suddenly and ending relatively quickly; or chronic, lasting for weeks and recurring periodically. Signs of colitis include blood and/or mucus in the stool, diarrhea and frequent defecation of small amounts of feces. Chronic colitis may result in weight loss. Dogs with colitis can be managed through diet or a combination of diet and medication.
What causes colitis?
The more common causes of colitis include:
- Parasites such as hookworms, roundworms, whipworms or giardia
- Food allergy
- Bacterial, viral or fungal infections
- Eating nonfood items such as grass, plastic or fabric
How can I reduce the risk that my cat will get colitis?
- Bring your cat in for regular fecal checkups with your veterinarian
- Keep garbage and spoiled food away from your cat
- Keep an eye on your cat—and what he or she eats—while outdoors
How is colitis managed?
Your veterinarian may prescribe medication for your pet. He or she may also recommend a special diet and/or dietary supplement that provides nutritional support for your pet with colitis.
