The Mad Cat Purrfect Pineapple is a tropical treat for your cat! This fun and quirky toy is 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.
