The best litter box for a cat with arthritis has a low entry, plenty of room inside, soft litter, and a spot your cat can reach without climbing stairs.
If your senior cat has started hesitating at the box or leaving accidents beside it, they're not being stubborn. Stepping in, squatting, and turning can hurt, and a few simple changes can make toileting much easier.
Key Takeaways
How Does Arthritis Affect Litter Box Use?
Arthritis makes the movements a cat needs for toileting, like stepping over an edge, squatting, and turning around, stiff and painful.
It's also very common. According to NC State's Comparative Pain Research and Education Center, over 90% of cats show signs of joint disease on X-rays as they age. Since cats hide pain well, changes in the litter box are often among the first clues.
A tall edge, a cramped box, or a long trip upstairs can all turn a quick visit into a struggle. Our post on early signs of arthritis in cats covers other changes to watch for.

Is It Arthritis or Something Else?
Many medical conditions can cause accidents outside the box, so a vet check always comes first.
Cornell Feline Health Center lists urinary tract inflammation, kidney disease, thyroid disease, diabetes, and digestive problems among the common causes. Your veterinarian could ask for a urine sample for testing, and a non-absorbent litter like Nosorb Non-Absorbent Cat Litter for Urine Collection can make collecting one at home easier, if your vet recommends it.
Choosing an Arthritis-Friendly Litter Box
The right litter box for cats with arthritis is easy to step into, roomy enough to turn in, and stable underfoot.
- Low entry. Your cat should walk in without lifting their legs high. The Van Ness Cat Litter Pan has a low entry area designed with older cats and cats with limited mobility in mind.
- Plenty of room. The Feline Veterinary Medical Association suggests a box about 1.5 times your cat's length, from nose to the base of the tail. That extra space matters even more in a senior cat litter box.
- Open, not covered. Most cats prefer uncovered boxes. Lids trap odors and make turning harder.
- Steady footing. A mat in front of the box gives sore paws a secure place to step. The Catit Non-slip Litter Mat has a non-slip backing and catches litter as your cat steps out.
What Litter Is Best for Senior Cats?
Soft, fine, unscented litter is usually the most comfortable choice for an arthritic cat's litter box.
- Choose a gentle texture. Coarse pellets or large crystals can feel rough on tender paws.
- Skip strong scents. Most cats prefer unscented litter.
- Keep it shallow. About 1 to 2 inches gives stable footing without sinking.
For a gentler feel underfoot, try World's Best Cat Litter Comfort Care Unscented, which has finer granules that are softer on your cat's paws.
Where Should You Place Litter Boxes for a Senior Cat?
Place litter boxes on the floor where your cat spends most of their time, in a quiet spot they can easily reach day and night.
- Keep it close. Long walks to the box can lead to accidents on the way.
- Avoid stairs. If your cat uses more than one floor, put a box on each level.
- Choose a calm spot, away from loud appliances, busy doorways, and food bowls.
Do Ramps or Cut-Out Entries Help?
Yes. A gentle ramp or a lowered entry can help a cat with mobility problems get in and out more comfortably.
- Cut-out entry: Cut down one side of a large plastic storage bin, then sand or tape the edges to smooth and round them.
- Ramp: If your box has a lip, a short, sturdy ramp with a non-slip surface can help. Make sure it doesn't wobble.
Making the Switch and Keeping It Clean
Make the change to the new litter box slowly, and keep the box clean. This way, your cat feels confident using the new box.
- Set the new box beside the old one for a week or two, with some familiar litter mixed in.
- Remove the old box once your cat uses the new one regularly.
- Scoop at least once a day. Sore cats are less likely to stand in a dirty box.
- Wash the box gently with soap and hot water every few weeks, and avoid ammonia-based cleaners.

Supporting Comfort Beyond the Litter Box
A cat mobility litter box setup works best as part of a wider comfort plan from your vet.
- Ask about pain relief. Your vet can recommend safe options for cats.
- Keep your cat at a healthy weight to ease strain on sore joints.
- Consider a joint supplement. Nutramax Cosequin Senior Joint Health Supplement for Cats comes in sprinkle capsules, while Nutramax Dasuquin Joint Health Supplement for Cats comes in soft chews. Both are made to support joint health.

When Should You Call the Vet Right Away?
Call your vet the same day if your cat is straining, crying in the box, or passing little or no urine.
- A male cat straining with little or no urine may have a urinary blockage, which is an emergency.
- Blood in the urine or stool needs prompt attention.
- Sudden trouble standing or using the back legs should be checked right away.
Frequently Asked Questions
Q1: How low should a litter box entry be for an arthritic cat?
Ans: If you want to buy a litter box for an arthritic cat, find one with a height comfortable enough for your cat to get on without lifting their legs too high. If your cat still seems to be struggling to step over, get an even lower box.
Q2: Why is my senior cat going beside the litter box?
Ans: Your cat might be in pain when stepping in or squatting, which is why they may go as close as the pain allows. Also, if you have a high edge or a small litter box, that can cause some issues. If the situation seems more serious, check with your vet.
Q3: Where should I place the litter box for a cat with arthritis?
Ans: Place the litter box on the floor for a cat with arthritis, in a quiet place away from food bowls. Make sure they don’t have to climb any stairs or uneven surfaces. If your cat roams on more than one floor, keep one litter box on each floor.
Q4: Does a cat with mobility problems need a litter box ramp?
Ans: Not necessarily. A low entry box itself is enough for a cat with mobility issues. However, if you see your cat still struggling, you can put in a short, sturdy ramp with a non-slip platform. Make sure the ramp doesn’t wobble, as it may scare your cat away.
Q5: Are large, low entry litter boxes better for senior cats?
Ans: Yes, generally large litter boxes are ideal for senior cats. It allows them to turn and squat over easily, which can be quite difficult in a low-entry box. While buying a litter box, try to find one that is about 1.5 times your cat’s length.
Q6: How can I stop litter box accidents caused by cat arthritis?
Ans: The first step is to take your cat to a vet to ensure there’s no other cause of pain or discomfort. Then, set up the litter box for cats with arthritis: a low-entry box with soft litter and a non-slip surface. Clean any accidents regularly.
With an easy-to-reach box, soft footing, and your vet's support, your senior cat can feel comfortable and confident again.
