Preventive measures for cat constipation:

1. Supplement fiber. Add more fiber to your cat's diet, such as switching to prescription cat food or providing cat grass. Hair-reducing cream can also be fed.

2. Increase drinking water. Increase the cat's drinking water, let the cat eat canned cat food or feed it homemade cat food, such as steamed fish without feed.

3. Strengthen exercise. Increase the cat’s amount of exercise and play with the cat more.

4. Clean the cat box. Clean the litter box in a timely manner and do not change the location of the litter box at will.

5. Comb the hair. Groom your cat more often to reduce the chance of the hair being swallowed.

6. Massage and defecate. Proper massaging of cats can promote intestinal peristalsis and help defecation.
