Cats love to kick and wrestle, and this cactus kicker promises all fun and no spikes! The Mad Cat Cactus Kicker is the purrfect size for biting, kicking, wrestling, and cuddling. Filled with a tempting custom blend of catnip and silvervine for twice the cat attractants, and twice the fun! Silvervine is an all-natural catnip alternative that cats love, it elicits a similar reaction to catnip, and works for many cats who normally are not affected by catnip.
