This snow monster is anything but abominable! With a super potent custom blend of catnip and silvervine, this yeti will have your cat yowlin' for more. Silvervine is an all-natural catnip alternative that cats love. It elicits a similar reaction to catnip and works for many cats that are not normally affected by catnip. Soft and lightweight, this two pack of toys is perfect for tossing, batting, chasing, and pouncing.
