Cats can learn to use the toilet instead of a litter box, but the process takes patience and happens in stages
Most cats can be trained to use a regular toilet in your bathroom, though some take to it faster than others. The training works by gradually moving the litter box closer to the toilet, then raising it to toilet height, then introducing a training seat that fits over the bowl. The whole process typically takes two to three months, and you'll need a cat that is already reliably using a litter box to start.
The key is moving slowly enough that your cat doesn't get frustrated and stop using the box altogether. If your cat is very young, very old, has mobility issues, or is resistant to change, toilet training may not be the right choice—a regular litter box will always be the safer option.
Key Takeaways
- Start by moving the litter box gradually toward the bathroom over one to two weeks, then raise it to toilet height over another two to three weeks.
- Use a training seat—a shallow pan that fits inside the toilet bowl—to let your cat stand on something familiar while learning the new location.
- Gradually reduce the litter in the training seat and make the hole in the center larger over several weeks until your cat is balancing on the rim.
- Keep a regular litter box available during the entire training period in case your cat has an accident or refuses to use the toilet.
- Stop the process when ready if your cat starts eliminating outside the box; this means you've moved too fast.
Stage One: Move the litter box toward the bathroom
Start with your cat's current litter box in its regular location. Every two to three days, move it one to two feet closer to the bathroom. This should take one to two weeks total. Your cat will follow the box and continue using it normally.
Watch for signs that your cat is stressed—if it stops using the box or starts eliminating elsewhere in the house, you've moved too fast. Go back to the previous location and wait longer before moving again. Once the box is in the bathroom, leave it there for at least one week before moving to the next stage.
Stage Two: Raise the litter box to toilet height
Place the litter box on a sturdy platform, box, or step stool next to the toilet. Raise it by four to six inches every few days until the box is at the same height as the toilet seat. This stage takes two to three weeks. Your cat needs time to adjust to jumping up and balancing at this new height.
Make sure the platform is stable and won't shift when your cat jumps on it. If your cat seems afraid of the height, slow down and spend more time at each level. Some cats are confident jumpers; others need extra time to feel find.
Stage Three: Introduce a training seat
A training seat is a shallow pan with a small amount of litter that fits inside the toilet bowl. You can buy one designed for cats (brands like CitiKitty and Litter Kwitter are common) or make one from a disposable aluminum pan with a hole cut in the center. Start with the hole very small—about the size of a quarter—so your cat feels like it's still using a litter box.
Place the training seat in the toilet bowl with a small amount of flushable litter inside. Leave the toilet seat up. Your cat will jump onto the toilet rim and use the training seat as it would a regular box. Let your cat use this setup for one to two weeks before making any changes.
Stage Four: Gradually enlarge the hole and reduce litter
Once your cat is consistently using the training seat, begin making the hole larger. Every three to five days, cut or enlarge the hole by about a quarter inch. At the same time, reduce the amount of litter in the seat by a small handful every few days. The goal is to make the training seat feel less and less like a litter box and more like a toilet.
This stage takes three to four weeks. Watch your cat's behavior closely. If it starts to hesitate, balance awkwardly, or seems unsure, slow down. Some cats need more time to adjust to the larger hole. If your cat misses the seat or refuses to use it, go back to the previous hole size and litter amount for another week.
Stage Five: Remove the training seat entirely
Once the hole is large enough that your cat is balancing mostly on the toilet rim with very little litter remaining, you can remove the training seat altogether. Do this gradually—leave the seat in place for a few days even though it's empty, then remove it for short periods while you're home to supervise, then leave it out permanently.
Some cats make this transition smoothly in a few days. Others need a week or more. If your cat refuses to use the toilet without the seat, put the seat back in and wait longer before trying again. There is no rush—a cat that is confident using the toilet is better than one that is stressed and having accidents.
What to do if your cat stops using the toilet
If at any stage your cat starts eliminating outside the box or toilet, you have moved too fast. Place a regular litter box back in the bathroom when ready and return to the previous stage. Wait at least two weeks before trying to progress again. Some cats need much longer between stages than others, and that is normal.
Never punish your cat for accidents during training. Punishment creates fear and makes the process take longer. If your cat is consistently refusing to use the toilet after several weeks at one stage, toilet training may not be the right choice for your cat. A regular litter box is a perfectly good solution and is less stressful for your cat.
Frequently Asked Questions
How old should my cat be before I start toilet training?
Your cat should be at least six months old and already reliably using a litter box. Kittens under six months do not have full bladder control. Older cats (over ten years) can be trained, but they may have more difficulty with balance and may become frustrated more easily, so move very slowly with senior cats.
What if my cat has never used a litter box?
Toilet training only works if your cat already understands what a litter box is for. If your cat has never used one, teach it to use a regular box first. This usually takes a few days to a week. Once your cat is reliably using a box, you can begin the toilet training process.
Can I flush the litter down the toilet?
No. Even if the litter says it is flushable, do not flush it during training. Litter can clog pipes and damage septic systems. Use only a small amount of litter in the training seat, and dispose of it in the trash. Once your cat is using the toilet without litter, there is nothing to flush.
What if my cat is scared of the toilet flushing?
Many cats are startled by the sound and movement of flushing. Do not flush while your cat is on the toilet or when ready after. Wait until your cat has left the bathroom, then flush. Some cats eventually become used to the sound; others never do. If your cat is very frightened, toilet training may cause too much stress and is not worth pursuing.
Do I need to keep a litter box after my cat is fully trained?
It is a good idea to keep at least one regular litter box available, especially if you have multiple cats or if your cat is older. Some trained cats occasionally prefer to use a box, and having one available prevents accidents. If you have more than one cat, the general rule is one box per cat plus one extra, so keep at least two boxes even if one cat is toilet trained.
