what do you feed them? I have my cats on purina one.. YES I know its bad for them, but they are very picky and all 3 have hairball issues and this is the ONLY food that they will eat so far that doesnt make them throw up on a daily basis. All 3 are overweight, they range in age from 9 years old to 3, all 3 were rescues, one was found as a 5 week old kitten and she has food issues, if she thinks the food is even getting a little low she will meow for hours untill you fill it. That all said, I want to get them on a better food. So I need some suggetions/expriences on what food you all feed and how well your cats do on it..thanks
