Litter Box Management and Cat Welfare

Inadequate litter provision is a leading cause of elimination problems and chronic stress in cats; following evidence-based litter management guidelines prevents both welfare and household problems.

Key Facts

The recommendation is one litter tray per cat plus one extra in multi-cat households
Covered litter trays may be avoided by cats that prefer not to be enclosed when vulnerable
Litter depth preference is typically 3-5 cm — shallower than many owners provide
Toileting outside the tray is the most common reason cats are surrendered to shelters

Welfare Considerations

Litter tray problems are frequently framed as cat behaviour problems when they are more accurately welfare signals — responses to inadequate provision, medical conditions, or inter-cat conflict. Cats that eliminate outside the tray are communicating discomfort with the current arrangement rather than wilfully misbehaving. Understanding litter provision as a welfare requirement rather than an optional convenience shapes the appropriate response: addressing the cause rather than punishing the symptom.

What You Can Do

Provide at minimum one litter tray per cat plus one additional in your household
Place litter trays in quiet, accessible locations not adjacent to food and water
Clean trays daily and consider the number, size, substrate, and location if problems arise
