Many at-home solutions are available for a cat with digestion problems.
Cat constipation happens when there is a buildup of feces in the bowel of the cat. The bowel helps to absorb water in the cat's stomach, when there isn't enough water, it becomes harder for the feces to be passed through the intestines. You can treat your cat's constipation with remedies you may have right in your home.
Canned Pumpkin
Canned pumpkin is one at-home remedy for cat constipation. Combine the canned plain pumpkin with your cat's normal cat food if she won't eat it alone. Most cats will be happy to lick it off a plate or spoon, however. Feed the cat about 1 to 2 teaspoons of this treat once a day.
Water
Water is the obvious at-home remedy for anything, but especially stomach problems such as constipation. Some cats don't drink as much water as needed and thus, as a result, may be constipated. Offer the cat plenty of extra water to help loosen up her bowel movements and pass them through her body.
