What's Included: The set features hollow bell rattle balls in three sizes (1.5", 2", and 3.7") and soft plush kicker toys in assorted colors. The size variety means the set works equally well for small kittens learning to bat and chase, and for larger adult cats who prefer a bigger toy to wrestle with. Why Cats Love It: The internal bell in each hollow ball produces a jingling sound during play that mimics the movement of small prey, triggering your cat's natural chase, pounce, and hunt behaviors. The plush toys provide a soft chewing and kicking outlet that helps redirect destructive behaviors like furniture scratching. Safety First: All ball toys are made from food-grade polypropylene (PP) plastic — BPA-free, lead-free, and phthalate-free — with smooth, burr-free edges designed to protect sensitive mouths during chewing. Plush toys use pet-safe materials and reinforced stitching.
