Start with the box in the old location, then move it slowly

The fastest way to get a cat to use a new litter box is to place it right next to the old one for the first week. Cats navigate by smell and habit, so moving the box suddenly to a different room often causes them to ignore it and go elsewhere in your home. Your cat knows where the old box is; the new one needs to feel like part of the same spot.

Once your cat is using the new box consistently while both sit side by side, move the old box away. If your cat stops using the new box after you remove the old one, put the old box back for another few days. The transition works best when it happens gradually—move the new box a few feet per day toward its final location, waiting a day or two between moves if your cat seems confused.

If you have more than one cat, keep the old box in place for at least two weeks. Multi-cat households need extra time because each cat may have a preferred box, and removing options too quickly creates conflict and accidents outside the box.

Key Takeaways

  • Place the new litter box next to the old one for at least one week so your cat can find it by smell without losing access to the familiar spot.
  • Move the new box only a few feet at a time toward its final location, waiting one to two days between moves.
  • Keep the old box available for at least two weeks if you have multiple cats, since each cat may prefer a different box.
  • If your cat stops using the new box after you remove the old one, return the old box and extend the transition by another week.
  • Clean the new box with the same litter or litter additive your cat already knows, since unfamiliar textures or scents can cause rejection.

Match the litter type and box style to what your cat already uses

Cats are particular about texture and smell. If you switch to a different litter brand, texture, or scent at the same time you introduce a new box, your cat may reject both. Use the same litter your cat is already using in the new box, at least for the first month. Once your cat is reliably using the new box, you can gradually mix in a new litter type if you want to change brands—add about 25 percent new litter to 75 percent old litter, then increase the ratio over two weeks.

The box style also matters. If your old box was uncovered and you buy a covered one, your cat may avoid it because the enclosed space feels different or traps odors. If your old box was large and you downsize, a smaller box may feel cramped. Match the size and style of the old box as closely as possible, then make changes one at a time after your cat is settled.

Clean the new box before the first use, then maintain it daily

A new litter box can smell like plastic or packaging material, which some cats find off-putting. Rinse the new box with warm water and let it dry completely before filling it with litter. Do not use soap or strong cleaners—the residue can deter your cat. Plain water is enough.

Once your cat is using the new box, scoop it daily and do a full litter change once a week. A clean box is more likely to be used consistently. If the box smells like urine or feces, your cat may start going elsewhere, especially if the old box is still available and cleaner.

Watch for medical issues if your cat refuses the new box

If your cat uses the old box reliably but refuses the new one despite a slow transition and matching litter, a medical issue may be the cause. Cats sometimes associate pain during elimination with the box itself, so they avoid it and use a different spot. Urinary tract infections, kidney disease, and digestive problems can all trigger this behavior.

If your cat has not used the new box after two weeks of gradual introduction, or if you notice straining, frequent trips to the box, or accidents outside the box, contact your veterinarian. A vet can rule out infection or illness before you assume it is a behavioral problem. Do not punish your cat for accidents—punishment increases stress and makes the problem worse.

Use litter attractants or pheromone products if your cat is hesitant

Some cats respond well to litter attractants—powders or sprays added to the new box to make it more appealing. Products like Dr. Elsey's Attract or Precious Cat attract cats by scent. Sprinkle a small amount on top of the litter in the new box, following the product instructions. These work best for cats that are straightforward cautious about change, not for cats with medical problems.

Feline pheromone products like Feliway can also help reduce stress during the transition. Spray Feliway around the new box (not on the litter itself) to create a calming scent that signals safety. These products are optional but can speed up acceptance in multi-cat homes or households where the cat is already anxious.

may support the new box is in a quiet, accessible location

The location of the new box matters as much as the box itself. Cats prefer litter boxes in quiet areas away from their food and water bowls, away from noisy appliances, and away from high-traffic household areas. If you are moving the box to a new room, choose a spot that is straightforward for your cat to reach at any time, including at night.

If the new location is far from where your cat spends most of its time, your cat may not bother to walk there. Place the box somewhere your cat naturally passes through, or in a room your cat uses regularly. Once your cat is using it reliably, you can move it to a less convenient spot if needed—but do so slowly, a few feet at a time.

Prevent accidents by keeping the old box clean during the transition

While you are introducing the new box, keep the old box scrupulously clean. If the old box becomes dirty or full, your cat will use it out of necessity and may not bother exploring the new one. Scoop the old box at least twice a day during the transition period, and do a full litter change every three to four days.

If your cat has an accident outside the box during the transition, clean the spot thoroughly with an enzymatic cleaner designed for pet urine. Regular cleaners do not break down the urine compounds that cats can smell, so they keep returning to the same spot. Enzymatic cleaners like Nature's Miracle or Rocco & Roxie remove the scent completely and discourage repeat accidents.

Frequently Asked Questions

How long does it usually take a cat to use a new litter box?

Most cats adjust to a new box within one to two weeks if you place it next to the old one and keep the litter the same. Some cats accept it in a few days; others take three to four weeks. The transition is faster if you move the box gradually rather than relocating it all at once.

What if my cat uses the new box but still has accidents elsewhere?

Accidents during a transition usually mean your cat is stressed or the new box location is not convenient enough. Make sure the new box is in a quiet, straightforward-to-reach spot, and keep the old box available for a few more days. If accidents continue after two weeks, contact your vet to rule out a urinary tract infection or other medical issue.

Can I use a different litter brand in the new box?

It is better to use the same litter brand at first, since cats can be picky about texture and scent. Once your cat is using the new box reliably for at least two weeks, you can gradually introduce a new brand by mixing it slowly with the old litter over two weeks.

Should I put the new litter box in the same room as the old one?

Yes, for at least the first week. Placing them side by side lets your cat find the new box by smell without losing access to the familiar one. After your cat uses the new box consistently, you can move it a few feet at a time to its final location.

What if I have two cats and only one is using the new box?

Keep both boxes available for at least two more weeks. Some cats prefer different boxes, and removing the old one too quickly can cause the reluctant cat to have accidents. You may eventually need two new boxes—the general rule is one box per cat, plus one extra.
