Cats may become fixated on certain food shapes and textures, not accepting anything unfamiliar as food. When cats will eat only certain textures and tastes of food, they suffer if put on special diets or if a favorite brand becomes unavailable. And good luck trying to trick the food-fixated cat by hiding pills!

Avoid the problem by feeding kittens and cats a variety of foods. Introduce new foods by hand when the kitten or cat is very hungry. Mix a small amount of new food in with favorites to encourage acceptance.

Feed kittens and cats a wide selection of foods in various flavors, sizes, textures and shapes. Vary treats and flavors to keep your feline flexible in the food department.
