Whether you have a young cat, an old cat or a mobility-challenged cat, the Kitty Go Here Cat Litter Pan just may be the purr-fect option for your home. Feline friends who are at least nine or ten years old may have a form of arthritis that can make it challenging to get in and out of litter boxes with higher walls. This paw-ticular litter pan has a low, 3-inch high entry, which also makes it a great option for training puppies and small pets like rabbits!
