Temptations are the ideal supplement to regular dry and canned cat food. Cats are notoriously finicky at times and these bits get them in the mood to eat their regular food. In this way they are like a rich appetizer for the main course.
I give a couple of these to my cats a few times a day. They get all excited just seeing me reach for the bag. When I rattle it, they go crazy. Treat time = happy cats.
