Four of my cats ate kibbles until they died. The half-meezer who had thyroid issues by about 12 was a picky eater, and by that time we had two others who ate anything. We switched to canned paté with lots of water to keep further urinary problems at bay for the males, and the thyroid female got fancy foods in little cans, with pickiness. I put her down at 15 because she continued downhill and was probably diabetic too. So the two remaining males, 15 come Easter, get the canned with water, and one of them goes across the street for the free buffet in the driveway.... ugh!
Our most adventurous cat, long gone, craved cucumber and cantaloupe. He could count to two half moons of cuke! Two others have loved black beans, plain or in olive oil. One of those (a current one) will steal anything on the menu. Fast as a snake, he is! Cooking is a pain because nothing At All can safely be left out except fruit and vegetables - so long as they are perfectly plain!
