Hi there,
I've never bought in to the breed specific food that more and more companies seem to offer these days. For me, when it comes to nutrition, a cat is a cat is a cat
They all have the same digestive system and the same nutritional needs - i.e. meat.
Although dry food in general is the least healthy food to eat for a cat, the best of the dry foods contain a high percentage of meat and a low percentage of other fillers such as rice, wheat, etc.
The two best dry foods available, regardless of breed, are Applaws and Orijen.
