Many cat owners are guilty of placing the litter box in a hidden, murky area. Stop doing this! Doing so only makes cat smells concentrate. Keep your cat’s litter box in a well-ventilated area, particularly near a window so the odors are easily dispersed. Enough lighting and space are also imperative. Cats like to move in and out of the area comfortably. If he finds it unpleasant, chances are, your cat will bury his treasure in the center of your bedroom next time.
