HuggleKats FlufferFleece Balls are a double dose of frolicking fun for HuggleKats everywhere! Weve transformed the softness of our best-selling HuggleFleecefabric into a three-pack of pure delight for cats. We've stuffed them with premium silver vine - a plant in the Kiwi family - that cats find even more alluring than catnip. Cats want to stay close to the source of the smell and immerse themselves in the aroma! Our three-pack collection also includes rattle, bell and crinkle.
