A little birdie told us what your cat needs in her toy box. The Peek-a-Bird™ Electronic Cat Toy has 2 play modes: set the toy to one-time-play or play-all-day mode to keep your cat engaged and entertained throughout the day. In play-all-day mode, the Peek-a-Bird's motion sensor will wake the toy if your cat walks by, and automatically wakes every two hours. With an opening on either side, the feather randomly peeks out and flutters, then disappears. Includes a replacement feather. Requires 3 AA batteries (not included). PetSafe® brand is here to help you and your pet live happy together™.
