For two cats, the recommended number of litter boxes is three-one box per cat plus one extra. This "N plus one" rule helps prevent elimination issues, territorial behavior, and litter box avoidance, ensuring each cat has enough space and privacy to use the box comfortably
. Additional considerations include:
- Place litter boxes in different locations or levels of the home to reduce territorial conflicts and provide easy access
- Keep the boxes clean by scooping daily and fully cleaning regularly to encourage use
- Choose litter boxes large enough for cats to turn around comfortably and consider your cats' preferences for open or covered boxes
While some bonded cats may share a box without problems, having three boxes for two cats is the best practice to maintain harmony and hygiene in a multi- cat household
