Separate the locations
A common starting point is one box per cat plus one extra. Several boxes pushed together offer fewer distinct choices than boxes placed in different quiet locations. Keep an escape route available and avoid trapping the cat beside noisy equipment.
Look at size and access
A cat should be able to enter, turn and dig comfortably. Consider entry height for cats with limited mobility. Covered and uncovered designs suit different individuals, so observe actual use rather than choosing only for human convenience.
Keep the routine consistent
Scoop regularly and follow the product’s cleaning and replacement instructions. Strong fragrances may be unwelcome. If changing litter, offer a gradual choice where practical instead of removing every familiar option at once.
Take changes seriously
Straining, frequent unsuccessful trips, blood or signs of pain need veterinary attention. Inability to pass urine can be an emergency. Do not punish accidents: investigate health, accessibility, cleanliness and household conflict.
A useful next step
Choose one manageable improvement and make a note of what changes. Use the practical tools to organize the details, and return to the discussion to share what you learned.
