Choosing a litter box for an older cat
A senior litter box should be large, stable and easy to enter, with a low opening and enough wall height to contain urine. Put an accessible option on every level the cat uses.

✓ Arthritis, weakness, urgency and cognitive change can all alter litter-box access.
✓ Offer large low-entry boxes on every used level, with non-slip footing and familiar unscented litter.
✓ Any new toileting change first needs a veterinary check for urinary, bowel, mobility or other disease.
A senior cat may avoid a box that now requires a painful climb or a long trip across slippery flooring.
The short answer
A senior cat may avoid a box that now requires a painful climb or a long trip across slippery flooring.
Why it may happen
Arthritis, weakness, urgency and cognitive change can all alter litter-box access.
Read the whole situation
One behaviour rarely has one guaranteed meaning. Compare it with your cat’s age, health, posture, appetite, litter habits, environment and usual pattern before drawing a conclusion.
What to do now
Offer large low-entry boxes on every used level, with non-slip footing and familiar unscented litter.
What not to do
Avoid punishment, forced handling and sudden large changes. They can add fear while hiding the information that would help you understand the original cause.
When to contact a veterinarian
Any new toileting change first needs a veterinary check for urinary, bowel, mobility or other disease.
Keep a useful record
Write down when it started, how often it happens and what immediately precedes and follows it. Photos, weights or short videos can make a veterinary or behaviour consultation more productive.
Remove the physical barriers
Choose a wide tray that allows turning without a deep climb. Place it on non-slip flooring along a short quiet route and keep familiar unscented litter. A low cut-out entrance with higher remaining sides can balance access and containment.

Investigate before blaming the box
Arthritis, weakness, urgency, constipation and urinary disease can all change toileting. Add the accessible box now, but arrange a veterinary check for any new accident, posture change or avoidance. Straining, blood or little urine is urgent.

Three simple things you can do
You do not have to change everything today. Pick one step that feels realistic, try it and see how your cat responds.

- 2Add non-slip flooring and keep a box on each used level of the home.
- 3Maintain the familiar litter texture while changing the box gradually.
Common mistakes
×Cutting an entrance with sharp unfinished edges.
×Replacing every box at once.
×Placing the accessible box far from the cat's resting area.
Questions cat people ask
How low should a senior cat litter-box entrance be?+
Low enough to step in without a high leg lift while still retaining litter. The ideal height depends on mobility, size and whether urine is directed over the edge.
Why does my older cat toilet beside the box?+
Pain, urgency, cognitive change, box access and medical disease can all contribute. Provide an easier box and arrange veterinary assessment rather than assuming stubbornness.
