Keep litter in and the dog out with Arm & Hammers Top Entry Litter Box. Designed to keep litter-loving dogs out, this litter pan features a top entry design that lets cats enter and exit through a wide opening on top of the pan, while the tall design keeps dogs from getting into the litter. This Top Entry Litter Pan is treated with Microban for built-in antimicrobial protection that stops the growth of odor-causing bacteria. To help stop litter scatter, the non-slip, textured lid has small cut outs that lets litter that may be stuck on your cats paws fall back down into the litter pan, keeping your floors clean and litter-free!
