Reasons for constipation in cats:

1. If the cat is obese or older, constipation will occur due to slower intestinal peristalsis.

2. When feeding a cat, if you often feed it some greasy and salty food, it will easily cause gastrointestinal discomfort and constipation.

3. If the cat has just entered a new environment and has not adapted yet, it may be reluctant to go to the toilet, causing constipation.

4. When the cat’s anus is blocked, it will cause anal pain and difficulty in defecation. Feces will accumulate in the intestines, causing constipation.

5. If the cat does not drink enough water, the water content in the feces will be less, so the feces will not be easily excreted from the body, causing constipation.

6. Cats that do not exercise enough can easily cause obesity and constipation.

7. Cats usually clean their bodies by licking their hair, causing hairball disease and constipation.

8. Many diseases can also cause varying degrees of constipation, such as renal failure, hypokalemia, and abnormal liver function.
