This product is a light-sensing, automatic cat teaser toy designed to stimulate your cat’s natural hunting instincts. Shaped like a caterpillar with multiple round segments and cute antennae, it attaches to windows or smooth surfaces using strong suction cups. The toy features a dangling feather or tail that moves automatically when it senses light or motion nearby, enticing cats to play. Built for hands-free entertainment, it provides mental and physical stimulation for your pet, helping reduce boredom and promote activity—especially when you’re not around. It’s ideal for indoor cats and playful kittens.
