The PetSafe Cheese Automatic Cat Toy is a fresh take on the classic cat and mouse pursuit. This interactive game of peek-a-boo includes 2 mice that pop out of a Swiss cheese block, keeping your cat busy on the hunt throughout the day. Give your cats spontaneous exercise by setting 3 separate automatic play sessions at random times throughout the day. During single play sessions, the timer automatically turns toy off after 10-15 minutes to conserve battery life. Requires 3 AA batteries (not included).
