The best thing to do, after reading, is to buy some raw meat and see what they think - I bought chicken, heart, liver and kidney (although couldnt deal with the kidney in the end!!), and just gave them all a few small chunks of each, to see what they thought - it went down best with my (at the time) eldest, who was toothless, the girls were fussy, one day they would, one day they wouldn't. I bagged up 3 chunks of each per cat in freezer bags, and just pulled out one each morning for their supper. I am not brave enough to completely do raw, so they get things like NAtures Menu and HiLife instead.
