just be a little careful about feeding them soley like this - taurine is a very important vitamin for cats that they have to ingest (i.e. take from their food) otherwise they get very ill. Cooking meat destroys taurine and in rwaw you have to feed the right proportions of meat, organ and bone to get this level right. So 80% muscle meat (including heart), 10% organ meat, and 10% bone for raw. It's a bit complicated first of all getting it all right on your own. I'm a wimp so get it from companies that have sorted out all the right ingredients and minced it for me (
www.food4-cats is one such place)
