Start with the right setup and location

A cat will use a litter tray most reliably when the tray is in a quiet, accessible spot away from their food and water bowls. Cats naturally avoid eliminating near where they eat, so placing the tray in a separate room or a far corner of the kitchen works better than putting it next to their food dish. The tray should be straightforward to reach — if your cat has to navigate stairs, jump over obstacles, or pass through a door they cannot open, they may go elsewhere instead.

Choose a tray size that fits your cat comfortably. The tray should be at least one and a half times the length of your cat's body, so they have room to turn around and dig. A tray that is too small or too high-sided can discourage use, especially in kittens or older cats with mobility issues. If you have multiple cats, the general rule is one tray per cat, plus one extra — so a two-cat household should have three trays in different locations.

Key Takeaways

  • Place the tray in a quiet, accessible location away from food and water, and use one tray per cat plus one extra.
  • Fill the tray with 2 to 3 inches of litter, and scoop waste daily to keep the tray clean and encourage regular use.
  • Place your cat in the tray after meals, naps, and playtime, and praise them calmly when they use it.
  • If your cat has an accident outside the tray, clean the spot thoroughly with enzymatic cleaner to remove the scent and prevent repeat accidents.
  • Avoid punishing accidents, as this creates fear and makes training harder — instead, focus on rewarding correct tray use.

Fill the tray with the right litter and depth

Most cats prefer fine-textured, unscented litter that feels similar to sand or soil. Clumping litter is easier to maintain because urine and feces clump together and can be scooped out daily, keeping the tray fresher longer. Fill the tray to a depth of 2 to 3 inches — this gives your cat enough material to dig and bury waste, which is a natural instinct.

If your cat has never used a tray before, start with a litter type that mimics outdoor soil: fine-grain, unscented clumping litter works for most cats. Some cats are sensitive to litter texture or scent, so if your cat avoids the tray, try switching brands or types. Keep the tray clean by scooping out clumps and solid waste daily — a dirty tray is one of the most common reasons cats stop using it.

Place your cat in the tray at key times

Cats are most likely to need the tray after eating, after waking from a nap, and after playtime. For the first week or two, gently place your cat in the tray at these times and let them explore. Do not force them to stay or dig — straightforward place them inside and step back. If they use the tray, stay calm and offer quiet praise or a small treat. Avoid loud celebrations, which can startle them and create negative associations.

If your cat leaves the tray without using it, do not be discouraged. Repeat this routine several times a day. Most cats will begin using the tray within a few days to a week once they understand where it is and what it is for. Kittens typically learn faster than adult cats, but adult cats can learn at any age.

Handle accidents outside the tray calmly

Accidents happen during training, and how you respond matters. If you catch your cat in the act, gently pick them up and place them in the tray. If they finish in the tray, praise them. If the accident has already happened, do not punish or scold your cat — punishment creates fear and makes them less likely to use the tray, not more.

Instead, clean the accident spot thoroughly with an enzymatic cleaner designed for pet urine. Regular household cleaners do not break down the urine compounds that cats can smell, so they may return to the same spot. Enzymatic cleaners contain bacteria that digest these compounds and remove the scent completely. Follow the product instructions for soaking time, which is usually 10 to 15 minutes. Once the spot is clean, your cat will have no scent marker telling them to go there again.

Troubleshoot if your cat avoids the tray

If your cat consistently avoids the tray after a week of training, check these common issues. First, make sure the tray is truly accessible — place it in the room where your cat spends the most time, and may support they can reach it without obstacles. Second, try a different litter type or brand; some cats are particular about texture or scent. Third, add a second tray in a different location, in case your cat prefers one spot over another.

If your cat is an adult and has used a tray before but suddenly stops, this can signal a medical issue like a urinary tract infection or digestive problem. A veterinarian should rule out health problems before you assume it is a training issue. Once medical causes are ruled out, return to the basics: may support the tray is clean, accessible, and in a quiet location.

Maintain the tray as your cat matures

Once your cat is reliably using the tray, your job is to keep it clean and functional. Scoop daily to remove clumps and solid waste. Replace the litter completely once a week, or more often if you have multiple cats or notice odor building up. A clean tray is the single best way to prevent your cat from seeking other spots.

As your cat ages, monitor their tray use. Older cats may need a tray with lower sides for easier entry, or a tray placed on the same floor where they spend most of their time to avoid stairs. If your senior cat begins having accidents, a veterinary check is important — changes in litter tray habits often reflect changes in health.

Frequently Asked Questions

How long does it usually take to train a cat to use a litter tray?

Most kittens learn within a few days to a week. Adult cats may take one to two weeks. Some cats catch on in a single day, while others need more time and repetition. Consistency in placement, cleanliness, and routine is more important than speed.

What if my cat uses the tray sometimes but not always?

Inconsistent use usually means the tray is not clean enough, not accessible enough, or there is a medical issue. Try scooping more frequently, adding a second tray in a different location, and scheduling a veterinary check to rule out urinary or digestive problems.

Can I train an adult cat that has never used a tray before?

Yes. Adult cats can learn at any age. Follow the same steps: place the tray in a quiet, accessible spot, use fine-textured litter, and place your cat in the tray after meals and naps. Adult cats may take longer than kittens, but most will learn within two to three weeks.

Should I use a covered litter tray or an open one?

Open trays are generally better for training because they are easier for your cat to access and you can monitor use more easily. Some cats prefer covered trays for privacy, but covered trays can trap odor and are harder to keep clean. Start with an open tray during training, then switch to a covered one later if your cat prefers it.

What litter should I avoid?

Avoid heavily scented litters, clay-based non-clumping litters, and crystal litters unless your cat has shown a preference for them. Most cats prefer fine-textured, unscented clumping litter. If your cat avoids the tray, the litter type is often the culprit — try switching before assuming a behavioral problem.
