About a month ago I rescued 2, 5 week old kittens off the side of the road. They were really skinny and weighed about 11 oz. They are doing alot better now and love people. The only problem is that when I feed them they just attack their food and eat until it is gone. I want them to just eat when they are hungry and I have tried to just put out food but they will eat till they throw it up and then more. I can't keep them and I am going to give them to one of my friends who wants them for barn cats or I wouldn't mind. Does anyone have a suggestion about how to start them on a free feed program?
