Make sure she has plenty of water. You can add 1 teaspoon of pumpkin (NOT pie filling) per 10lbs body weight once or twice daily. Mix well into the food. Canned is preferred since it contains more moisture which will aid defecation. Too much pumpkin may cause diarrhea. It should not cause pain. If Mishka is painful, have her examined by your veterinarian.

    To keep her regular I would increase the fiber in her diet. I would add a tablespoon of canned pumpkin to each feeding. This will prevent constipation and help with diarrhea also. If she wont eat the pumpkin you can sprinkle a capsule of plain Metamucil on the food. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Freckles.

    Constipation in cats occurs when cats have infrequent, hard bowel movements, often with some degree of straining. Given Carat's infrequent bowel movements, it sounds quite likely that she has some degree of constipation. My goal for cats that can suffer from constipation is to get them to a point where they have a normal (not too hard/not too soft) bowel movement every day without straining. If a bit of mashed pumpkin keeps Carat regular, feel free to give her a small amount regularly. However, if her constipation issues seem to worsen, it would be best to take her to the vet. Some cats require stool softeners on a chronic basis. I hope this helps and that all goes well for Carat!
