This website rates cat foods on a point scale based on the absence of undesirable ingredients, such as wheat gluten, and the presence of desirable ingredients, such as meat instead of meat by-products. Ratings reflect the importance of reading labels, as different varieties of the same brand can have widely different scores like the fancy feast canned foods. Click on the brand that you want to know about. 

This is by far one of the best all-around cat information site on the web.

In terms of food, the site features listings of the top ten dry and top ten canned cat foods, written by site guide Franny Syufy who has spent 10 years researching and studying feline nutrition.. The guide notes that none of the products named in her lists of top premium dry and canned cat foods contain wheat gluten, and none were recalled as of mid-March 2007. (Note that ConsumerSearch.com is owned by About.com/The New York Times.)

How To Choose Cat Food

Pros and Cons of Homecooking for your cat 
Read the article at www.peteducation.com on Home Diets 
If you are going to homecook for your feline you need to be consistent! 
Homecooking does NOT mean table scraps. 
The diet should be supplemented with a daily vitamin to ensure a balanced diet. 
Your veterinarian sells vitamins.
The advantage of the commercial products is that someone else does all the calculations and manufactures the food so that it is generally consistent, but there is absolutely 
no reason you can't feed YOUR cat a homemade diet if you ARE consistent.
