I'm looking for a highly palatable dry or semi-moist food for a sick cat. I normally feed Nani canned food but I need something to leave in the bowl for when I'm not at home. If she doesn't have something to eat she will eat her paper litter (because she's anemic). I can't leave canned food in the bowl because it will spoil. I would only need the dry or semi-moist food for maybe once or twice a week for a couple hours or possibly for an entire weekend once a month. She stopped eating two different dry foods. I would normally try something like Tender Vittles but it was discontinued in the USA. Any suggestions?
