✓ Cleanliness is only one factor; pain, box design, substrate, location and fear can all matter
✓ Book a health check and offer a larger easy-entry box with familiar litter in a separate quiet location.
✓ Constipation, diarrhoea, blood, vomiting or repeated straining needs prompt veterinary care.
Cleanliness is only one factor; pain, box design, substrate, location and fear can all matter. Punishment increases stress and does not reveal the cause.
The short answer
Cleanliness is only one factor; pain, box design, substrate, location and fear can all matter. Punishment increases stress and does not reveal the cause.
What to observe
Note stool quality, box entry, turning, digging and any interruption by people or pets.
How to read the situation
Punishment increases stress and does not reveal the cause. Compare the pattern with your cat’s usual behaviour and consider timing, body language, appetite, litter-box use, mobility and recent changes.
What to do now
Book a health check and offer a larger easy-entry box with familiar litter in a separate quiet location.
What not to do
Do not punish, frighten, force or repeatedly test the cat. Avoid changing several things at once, because that makes the response harder to interpret.
When to contact a veterinarian
Constipation, diarrhoea, blood, vomiting or repeated straining needs prompt veterinary care.
What to record
Write down when it began, how often it happens and what occurs immediately before and after. A short video, clear photo, food record or litter record can give the veterinary team useful context.
What to check first
Check stool consistency, straining, box size, litter type, location and whether urine still goes inside.

What to do next
Add a large open box at the chosen spot with unscented litter and arrange veterinary advice if the change repeats. Constipation, diarrhoea, blood, vomiting, weight loss or pain needs prompt veterinary assessment.
