Duffy's eating pre-packaged raw from a local BC company called Natural Instincts recommended by my holistic vet. She loves it
Have a look @ the ingredients to make sure there is bone for calcium, should have organs (heart/liver/kidneys) and not too much veggies ~ for cats should be 5% or less
If you can get them to eat a variety of meats - even better. Chicken, Turkey will have bone in, Rabbit may or may not (will show on the label), Beef & Lamb won't have bone in it. You should have @ least 1 red meat for added iron, though they will get some in the organs.
