The Mad Cat Brunch Buddies two pack is the perfect way to wake up from a catnap! Adorable plush filled with a unique blend of premium catnip and silvervine that’s maximum potency, pure, and pesticide free. 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.
