Ultimate playtime with the automatic cat toy plate. The automatic Catmaster from Swisspet will delight your cat. The special cat play string bounces in and out, encouraging your cat to play for hours. The rotation rhythm of the play string automatically changes from slow to fast and back to slow, making it even more exciting and varied for your cat. Watch as your curious cat tries to catch the string before it disappears again. Seconds later, the string reappears. Batteries not included (requires 3 AA batteries).
