Cat Food - Whats the best out there? And where can you buy it from?

I guess it depends on your cats and what they like. Mine's quite fussy and I've tried him on everything from Whiskas, Go Cat, Iams, James Wellbeloved, from tins, to trays to pouches etc, and he'll only actually eat Felix pouches and Go Cat Biscuits. He likes the jelly and supermeat ones but he doesn't like anything in gravy really, so if I were you I'd feed your cats what they like to eat.
