The Rolo Rat Automatic Cat Toy keeps your cat active and entertained with random movements and a quick moving tail to chase and pounce on. After installing the batteries (3x AAA, not included), turn the toy on by pressing its nose, and it will begin rolling around and making sounds that attract your cat. Your cat will enjoy trying to catch the tail as it whips around, and chasing the eyes that light up. After 15 minutes of playtime, the toy will automatically shut off to let your cat rest, and it can be turned back on at any time. Hold down the nose button to turn on “Play While You Are Away” mode. This mode turns the toy on for 15 minutes every two hours. After three 15-minute playtimes, the toy will shut off until you turn it on again. By encouraging your cat to exercise and providing mental stimulation, this toy helps keep your cat happy and healthy.
