I have a 19-year-old cat who is (now) on a low-protein diet, precluding the canonical week of tuna. Is there someplace I can buy chametz-free, low-protein food? Are there any consequences (for me) if the cat eats kitniyot? (Owning kitniyot is permitted, I know, and the cat has his own dish and spoon.)
This list from the Star-K has many items that you can feed your cat on Pesach.
