Cat food puzzles are exactly what they sound like. The puzzles can be any object that holds food and requires your feline friend to figure out how to get it. The puzzles come in all sorts of shapes and sizes. Food could be cleverly hidden inside a ball or other mobile device and only by rolling it or pushing it will the cat capture the tasty treat. Other puzzles are stationary with cups or holes that require cats to fish out their wet or dry food with a paw.
