The Catstages Ball Treat Stuffer blends playtime with treat time for the best of both worlds. Stuff with your cat's favorite wet or dry treats, send the ball rolling, and unleash your wild cat's hunting instincts as they chase their treat-dispensing prey. Varying textures around the ball cause erratic movements cats can't resist. This treat ball is soft yet durable for long-lasting fun, and is semi-translucent to tempt even the most unimpressed felines. The best part? Figuring out how to release the tasty rewards provides both mental stimulation and physical exercise. Cats use their hunting instincts to chase, bat, and swat at their prey, satisfying their need for a mental challenge and energy exertion. The Catstages Ball Treat Stuffer keeps curious cats busy and helps bust boredom while your cat plays, bringing all the more benefit to your cat's playtime.
