JC has an iron-clad stomach, and he dictates when and how his dry food is rotated. He refuses to eat the same brand more than twice a week, so I buy three different brands, usually in 2 kg. bags, and feed them on consecutive days (right now Solid Gold, Eukanuba and Innova). After he has been eating a brand that way for about 3 - 4 months, he stops eating it, so I have to replace it with something else (Felidae and Nutro will be on offer next). He's not quite as bad with canned food because of the different flavors available, so I can stick to the same 3 or 4 brands (Innova, Solid Gold and two European brands). However, the food has to be in little (2 - 3 ounce) cans, and pouches or aluminum foil dishes are unacceptable. No diarrhea or vomiting, so I give into his demands.
