I have a cat who has been dealing with diarrhea and it is now much improved. He was put on some medications because his diarrhea had progressed so much that an infection was occuring in his bowels. This was detected through blood tests that showed his white blood cell count was very high. As well, an ultrasound was done that showed that the inflammation was in the lining of his bowels so the vet determined that was where the infection was located. But it was ultimately decided that the diarrhea was caused by a food allergy that was not known to us until now. He had diarrhea for years and it was always thought that he had a case of IBD and we tried to control it with Prednisilone (steroids) but thankfully it is clearing up very well with a change of diet and another drug called Metronidazole that we are hoping he will only need for short time.
He may still have IBD but now we feel that it is aggrevated by certain foods.

He was put on to a very gentle/bland diet called Medi-Cal Gastro and then slowly switched over to Medi-Cal Hypo Gastro. He is doing very well. He has had a few relapses that occured when I tried to feed him Hills I/D. I believe the reason for this is because he is dealing with a food allergy and while I/D is mild, it probably has ingredients in it that don't agree with him. Once I stopped feeding the I/D and went back to the HypoGastro, the diarrhea stopped.

As others have mentioned, I wonder if your cat is possibly dealing with a food allergy. The HypoGastro has limited ingredients in it that are not common and it works well for cats that have allergies that can lead to diarrhea.
There is another food made by Hills called Z/D that is also a hypoallergenic diet.

You mentioned that you have your cat on a mix of I/D and cat chow. You may want to try and just feed one kind of food because the mixture may be upsetting to your cat's stomach. But you might be in the process of weeding out the cat chow to switch over to the I/D?

I hope your kitty begins to feel better soon.
