This is an interesting product that has three different types of plant materials that are known attractants for cats. Clumps of catnip, silvervine, and gall nut have been compressed into ball shapes. The three balls fit into a mount that can be attached to the wall or just set on the ground for kitty to investigate. The idea is for your kitty to rub, lick, and/or scratch the materials for benefits to mental and physical health.
Read the reviews of this popular cat treat product to get an idea if it might be worth a try for you and your kitties. We have offered our cats silvervine sticks and they don't seem to show any interest. We have also offered compressed catnip balls and our cats are far less interested in those than in catnip flakes or fresh nip. But after looking at the cute photos with the reviews for this Peteast Catnip Toy, I think we'd give it a try.
