I'm sorry to hear that your cat is constipated. My Sky was also slightly constipated and I asked my vet about it and she said to try giving him some canned pumpkin. I mix it in with some of his wet food. It has a lot of fiber in it so this should help with constipation. It's also great for binding stools for a cat with diarrhea too. She also said that if this doesn't work then I could try some other over the counter laxatives. I forgot the names of them though.

Before I asked my vet about Sky, I found some information on a website that said to use mineral oil. My vet said that this wasn't a good idea because it can become trapped in the cats lungs and cause problems. Pumpkin is the most natural and noninvasive thing to use on your cat. Good luck.
