Hi, I came across your post on this site as I was searching cures and remedies for my cat. I can see your post was back in 2007, but I just want to see if you found a cure for your cat as it sounds like my cat has similar symptoms. Basically my cat is 3 years old and she has been having diarrhea for over 6 months now. I have taken her to multiple vets and specialists and did all sorts of tests, x-rays and ultra-sound. The vets didn't find any parasites and we treated her for pretty much all sorts of parasites if they do exist. The vets have ruled out cancer so basically its IBD which my cat's internal intestinal is very inflamed throughout. My vet bill has amassed to couple thousand dollars already and I cannot commit further to spending another couple thousand for biopsy and endoscopy. So now my cat is basically on a steroids and antibiotics medication daily and it doesn't seem to improve at all. Recently I noticed that my cat is licking her anus more than usual and that it looks red at times like it was inflamed and I can also hear more gas coming out too. My vets never did any sort of anal expression since my cat is very protective and sensitive about being touched back there. I do try to wipe my cat's anus gently often and she would let out meows here and there. I guess with number of times she has been having diarrhea daily, I am sure its causing her anus to leak too. I appreciate if you can give me any sort of advice or findings that you came across for your cat. Thanks.
