✓ 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.
The short answer
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.
What to observe first
Compare the moment with your cat’s usual pattern. Note timing, frequency, body language, appetite, litter-box use, mobility and any recent household change.
Why the setting matters
The cat may be trying to use the box correctly but cannot turn or squat comfortably. One isolated detail rarely explains behaviour or health on its own, so look at the whole cat and the immediate environment.
What you can do
Arrange a veterinary check and add a large low-entry high-backed box on every needed level.
A gentle way to test it
Make one small safe adjustment and give the cat time and choice. Avoid punishment, forced handling and several changes at once, because they make the response harder to understand.
When to contact a veterinarian
Straining, blood, frequent attempts or reduced urine is urgent.
Prepare useful information
Write down when it began and how often it occurs. A short video, clear photo, food record or litter record can help a veterinary professional assess a pattern that may not appear during the appointment.
Make access easier today
Offer a large low-entry uncovered box on every used level, with familiar unscented litter and non-slip footing. Place it near the cat's normal route without trapping them in a corner. Keep boxes clean and well lit at night.

Record the exact toileting pattern
Note whether urine or stool lands beside the tray, whether the cat enters partially and whether there is straining, increased frequency or changed output. Little or no urine is urgent, especially in a male cat.

Urinating at the front of the box often indicates limited space, entry preference, pain or a box the cat cannot position in comfortably.
