The Yeowww! Catnip Fish Cat Toy is artistically designed, sewn by hand, and individually stuffed with 100% organically grown catnip from trusted farmers. The outer fabric is a durable cotton twill that’s strong enough to hold up to all the biting and bunny kicking a cat can dish out. The Yeowww! Fish is brightly colored and quirky and has no cotton fillers, dangerous plastic pieces or any of the cheaper “toy grade” materials.
