A cat needs exercise, like in nature, in order to get its food. This small toy, called Pipolino, forces the feline to play with it befire it releases food. There is little worry that the cat will leave pellets strewn all over your floors because of the principle of least effort. It's easier for the cat to eat the pellets on the floor than spill more pellets. Pipolino costs approximately 40 USD (29.90 euro).
