I don’t know of any, but check out catinfo.org. There is lots of information regarding different brands of cat food;the site belongs to a Vet, Dr. Pierson. She does not rank the food so much as she provides the nutritional content of different cat food and how they can affect the health of your cats. Here’s some links to the site:

There is also a thread named “cat food recommendations” started by Akari_32 here. You can find it under the off topic forums. Read through it or just post a question and maybe one of us can help you through our experiences in trying to find cat food for our fur babies. 😉
