I absolutely would not feed my cats raw minced meat nor factory farmed chicken. I have fed them corn fed free-range chicken, but they've gone off it.
Mostly they eat some tinned salmon or mackerel or sardines or Fancy feast Royale along with Hills science diet Furball Senior and Royal Canin Renal for the older cat with kidney failure. With her it's been a question of letting her eat whatever she wants as her weight loss has been an issue. But since winter she has been eating more dry food which is calorie rich and wears a nice warm coat to save her expending calories keeping warm and she has started to put on a bit of weight.

I've tried all the raw chicken wings thing and the home-made with rice and what have you stuff and they just won't go near it!
