I would like to know too. It's good info to have in case it happens to your kitty. my cat had a bad experience a couple years ago with her stomach. of course it was diarrhea (dehydration).

I Left a stick of butter/margerine out for my cats. The would lick up some of the butter every now and again and it greatly reduced the amount of hair ball troubles they were having. For the most part the hair balls jsut seemed to pass through. It might work for you fellows too.

I've heard 100% pure pumpkin helps with constipation. I'd look into that and see if it's true.

I would think it's mainly about the food he's eating. Cats have very fussy systems and if there is too much filler or stuff that cats cannot digest, then that usually causes a problem. In all my conversations with vets over the past years, they are very consistent to say avoid the grains and carbs. Cats need protein and fat and nothing else. All those special "indoor" blends with extra grains are really not healthy for our beloved furry ones. My current vet is also a big opponent of fish and chicken, saying that beef foods are better for them. We discussed this on another thread. I forget the subject. Cat food or something rather obvious, I think.

Of course, there could be other issues - stress, other medical problems, etc. But my gut instinct (no pun intended) tells me this is probably about the tummy and what we put it in it.
