Best Overall: Dr. Elsey's Precious Cat Ultra Cat Litter
Even apartment dwellers love Dr. Elsey's, remarking that it is one of the only litters that eliminates smells, even in tiny spaces. Additionally, it works well for multiple cats, though we would recommend changing the clutter a little more frequently. Precious Cat Ultra is offered in 18 lbs or 40 pounds; pouring it out of the plastic bag can be cumbersome, so we recommend a kitty litter container to make it a bit easier. Dr. Elsey's is among those top-rated litters on Amazon, and for good reason. It's a dust-free, non-scented and clumping litter that makes for cleanup. The formula utilizes heavy granules, which reduce tracking as soon as your cat leaves the box, and is hypoallergenic--so that the finicky cats will not have a problem using it. Additionally, it is designed to reduce liquids from hitting the bottom of the tray, so you won't spend your evenings scraping up congealed litter. Even though it's odor and perfume-free, the medium-weight clay has been devised to reduce odors by trapping them inside.
Best for Multiples: Arm & Hammer Clump & Seal Multi-Cat Litter
Understands the struggles of maintaining a fresh litter box. They wind up using the one way, although we recommend a minumum of one litter box for every cat. Make cleanup easier and to lessen odors, we adore Seal Multi-Cat & Arm & Hammer's Clump clutter. It includes a 7-day warranty that is odor-free, and is devised to make during cleaning clumps that will not fall apart. It is created out of Arm & Hammer Baking Soda, which can be demonstrated to reduce smells and can be nearly completely dust-free.
Reviewers do note that it's a powerful"clean" odor, which may not be to everybody's taste. But if you are trying hard to keep your home smelling cat-free, Hammer's & Arm clutter is a good selection for houses.
