But it's even better when you play, too! Drag this toy by the tail to simulate a scampering rodent, and you'll stimulate your cat's natural hunting instinct. Indoor cats, especially, need opportunities to act out their natural hunting instincts and to get the kind of exercise a toy like this can provide. Catch a Mouse by the Tail comes in its own zippered pouch, which you can keep and use to store this special toy when it's not in use.
