Pets

Had really bad IBD. We had rescued her. In Hong Kong, they put her on prednisone, which helped. We then moved to Japan. My vet there said, “we have got to get her off this prednisone.” She was eating Science Diet digestive prescription food at the time. The vet in Japan said that she thought the science diet had actually caused the IBD. Stating that the science diet was not very good food. She said it was all marketing. She said, she has a food allergy and we have to figure out what it is. So, we started an elimination diet to figure out what was causing the horrible (and I’m talking horrible) diarrhea.
She said, we are going to start with eliminating chicken and only give her fish. She gave me a royal canin that was only sold in Japan that only had fish in it. No fillers. Just fish. Within 48 hours my cat had normal stools. She was basically cured. Turns out she was allergic to chicken. (We got lucky that the chicken was the one.) This was before the pet food companies started making single protein foods. When I moved back to the states, a friend in Tokyo would ship the food to me in NY from Japan, as it was not available in the US. This was 2007.
I finally, after 2 years, found a canned food that was only fish, no chicken. Back then, they put chicken in all cat food. She lived until
She was 18. Never had diarrhea after the vet in Tokyo figured it out. Pet foods do not have to be regulated by the FDA. And, those prescription diets are not what they say they are. My dog eats a raw diet. My current cat eats a brand called Rawz (which is family owned and all proceeds go to charity) that has no fillers. I would suggest trying individual proteins to see what is causing the problem. The prescription foods are marketing, crap, and expensive. Feel free to message me if you have any questions. I’ve been there with both of my cats and my dog.
