What is the best way to control litter box odors?
A … Scrupulously clean litter boxes have no smell. There are odor absorbing gels and odor control spray powders to help eliminate odors in and around your cat litter boxes. However, the best and healthiest way to control litter box odors is to keep it clean. This entails daily scooping of urine and waste clumps and at least weekly changing of the entire litter contents and any litter pan liners. You can simplify litter box cleaning with an automatic litter box. These rake away waste periodically throughout the day, often just a few minutes after your cat exits the litter pan.
