Fun, innovative, award-winning, and (best of all) CUTE. Meet iFetch, the dog toy that is changing the way pets and their humans play together. The iFetch runs on AC Adapter (included) or 6 C-cell batteries. Once powered up, select the distance that best suits your space by pressing the button on the rear of the machine. iFetch has three distance settings, 10, 20 or 30 feet. Once selected your dog drops the ball into the top and the ball is launched out of the machine, for your fetch crazy dog to chase & collect. It comes with 3 miniature tennis balls that are 1.6″ (40 mm) in diameter and an AC Adapter. It's the perfect fetch toy for small – medium fetch loving pups.
