Good afternoon! To a cat of 5 months. Eats "Oat-flakes" with a fish. Yesterday instead of a usual porridge of a distance perlovku. A cat has pulled out, though ate with pleasure. It can be reaction to groats? (groats has left undigested). Thanks.

Hello. There can be a reaction to groats, and there can be other reason. And perlovka, and oat-flakes, especially with a fish - are not normal meal for a cat.
