* '''Clay clumping''' size (c)lumps that are easily picked up by scoops. Requires minimal heavy maintenance, since relatively clean litter is left behind when clumps are removed. Should be fully replaced once a month.
* '''Clay non Absorbs, but doesn't clump. It requires more maintenance (replaced once a week) and odor control varies according to brand and the frequency of your cat's litter box use.
* '''Crystal based litter doesn't do the best for clumping, but it is good at absorbing odor. To clean it up you must completely empty the box once a week and replace it with new litter.
* '''Allfree. It makes for easy cleanup since it is flushable. Plus, it is great at controlling odor.
** Biodegradable litters include brands made from plant materials, wood, and paper. More than any of the above litters, these litter types won't stick to paws and track.
* '''Silica pellets''' Look like capsules or beads and absorb liquid, changing color when filthy and in need of change. In the meanwhile, only feces need to be scooped. Tracking won't be an issue.
