When we first bought our house we had two cats, Morgan and Catastrophie who had been free fed their whole lives. When we started being adopted by other cats it just kind of happened that they were then free fed, as we couldn't change habits the original two had for over 10 years. Our four get....oh my, I must need more coffee as I can't remember the name of the cat food!!!! Once I remember I'll post it...OH YEAH! Royal Canin.....thats it. Whew! I was starting to worry.....none of them seem inclined to over eat though...
