Keep your cat engaged in playtime with the ever-changing Jackson Galaxy Asteroid Puzzle Treat Toy that challenges and rewards them. Insert your cat's favorite treat, then give it to him or her for endless amounts of fun. As your cat learns how to get the treats out, you can push in the nubs to increase difficulty making it more challenging for treats to come out. The translucent outer shell allows your cat to see the treats inside while the small holes at the end of the nubs release the scent of the treats to keep your cat interested. The Jackson Galaxy Asteroid Puzzle Treat Toy engages "raw cat" instinct to swat and pounce while helping to build confidence. Works with most cat treats.
