I"ve bin raisng my own rats and mice for years I feed them dog food cat food left over people food. All my rat are very healthy they have piles of babys and they grow very big. Well this summer a breeder told me to feed Mazutrri or lab chow. He told me that dog food and cat food were know good that my rats would grow bigger and faster if I switched. So I gave it a try. I whent through two large bages and you know there was a big diferance! The price! that rat feed is so expensive it's joke! Dog food has worked fine for me for twenty years so I think I'll stay with it why fix something thats not broke!
