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. Catnip + Silvervine: Some cats LOVE catnip, but not all cats are affected by it. To solve this problem we developed our own unique blend of catnip and silvervine. Silvervine is a non-toxic, all natural catnip alternative that many cats actually prefer. This potent stimulant elicits a similar reaction to catnip, and is both safe and fun. Unique Design: Mad Cat toys come in a wide variety of unique, silly, playful designs that are unlike any other cat toys. These wild and wacky toys are designed to be fun for both cats and their owners. Mad Cat toys are perfect for posting photos with your celebrity cat, but even better for playtime! Mixed materials: Mad Cat toys are made of soft, high-quality plush with fun accents such as string, crinkle, embroidery and, of course, our custom blend of catnip and silvervine! Ideal for tossing, batting, kicking, and cuddling.
