Walmart offers the As Seen on TV Purrfect Arch Cat Self-Groomer and Massager, model no. PR011106, for $8.85. (Amazon charges the same with free shipping for Prime members.) Choose in-store pickup to dodge the $4.97 shipping fee. That's the lowest price we could find by a buck. It features a catnip-infused carpet base and is designed to reduce shedding, hairballs, and matting.
