The Categories Knitty Kitty cat toy brings it back to basics with an emphasis on the things cats love—yarn, balls and rattles. Although this may look like a typical ball of yarn, it is not! The Categories Knitty Kitty appeals to a cat's instinctive and playful behaviors and ensures stimulating playtime. Designed to last, the rattling Knitty Kitty does not unravel and can handle all of your cat's tossing, batting, chasing and pouncing fun.
