✓ Arthritis, balance, urgency, vision and box design can change positioning
✓ Arrange a veterinary check and add a large low-entry high-backed box on every needed level.
✓ Straining, blood, frequent attempts or reduced urine is urgent.
Arthritis, balance, urgency, vision and box design can change positioning. The cat may be trying to use the box correctly but cannot turn or squat comfortably.
Read where the accident happens
Urine or stool just outside the entrance may mean the cat enters only partly or cannot turn comfortably. Accidents elsewhere can reflect urgency, route difficulty, box avoidance or confusion. Do not assume stubbornness.
Make access easier today
Offer a large uncovered low-entry tray on every used level, with familiar unscented litter, good lighting and non-slip footing. Keep it near the normal route without trapping the cat in a corner.
Protect choice and cleanliness
Use more than one separated box, scoop at least daily and keep the route free of stairs or jumping where possible. In multi-cat homes, ensure another cat cannot guard the approach or exit.
What to record
Note whether urine or stool lands beside the tray, entry posture, straining, frequency, clump size, constipation, thirst, mobility and confusion. Photograph the setup and film natural walking without forcing movement.
When to contact a veterinarian
Arrange prompt assessment for any new pattern. Straining, blood, repeated visits, pain or little to no urine is urgent, especially in a male cat. Weakness, vomiting or collapse also needs immediate care.
