I switched most of my guys over to a raw diet about 2 years ago. One of them has irritable bowel syndrome that is made MUCH worse by commercial cat food.

There are plenty of days when they eat better than I do

I make there food a couple of times a week using chicken breast (raw and no bones), chicken liver (for the taurine), baked sweet potato, carrots, apples, sour cream, and pumpkin. Mine has quite a bit of fiber because of the IBS guy, but I can tell you that it has certainly cut down on hair balls from everyone else. I also order a supplement off the web so that I know they are getting a balanced diet.

I find that they are generally more healthy and active than when they were on the commercial cat food.
