What toilet training means and whether your cat can do it
Toilet training a cat means teaching your cat to use your household toilet instead of a litter box—sitting on the seat, balancing, and doing their business in the water below. Most healthy adult cats can learn this over weeks or months, though some never fully adjust and that is fine. The process works best with cats over one year old who already use a litter box reliably.
This is not a quick fix. You will need patience, a training seat that fits your toilet, and a willingness to go backward if your cat gets stressed. Some cats take to it naturally; others prefer the litter box and should be allowed to keep one. The goal is to give your cat the option, not to force the change.
Key Takeaways
- Toilet training happens in stages: moving the litter box closer to the toilet, raising it to seat height, introducing a training seat with litter, then gradually reducing litter and enlarging the hole.
- The process typically takes four to six months, and rushing any stage causes most cats to stop using the toilet and return to accidents elsewhere.
- You will need a training seat (a plastic ring with a litter pan that fits inside your toilet bowl) and a sturdy step stool so your cat can reach the seat safely.
- If your cat stops using the toilet at any point, move back one stage and stay there longer before trying again.
- Some cats will never toilet train, and keeping a litter box available prevents stress-related behavior problems.
Gather the equipment before you start
You need three things: a training seat (also called a toilet training kit), a step stool, and patience. The training seat is a plastic ring that holds a small litter pan and sits inside your toilet bowl. Common brands include CitiKitty, Litter Kwitter, and Potty Training Kit for Cats—they cost between $20 and $50 and are sold online and at pet stores. Pick one with a removable litter pan so you can clean it easily.
A sturdy step stool is essential. Your cat needs to reach the toilet seat without jumping from the floor, which is stressful and unsafe. A wooden or plastic step stool 8 to 12 inches high works well. Test it for stability before your cat uses it—a wobbly stool will scare your cat away from the toilet permanently.
You will also need flushable litter or regular litter you can scoop out. Do not flush regular litter down the toilet; it clogs pipes. Flushable litter (made from corn, wheat, or pine) breaks down in water, though some plumbers still recommend scooping it out rather than flushing. Check your training seat instructions for what litter works best with that model.
Move the litter box toward the toilet over one to two weeks
Start by moving your cat's current litter box a few feet closer to the bathroom each day. Your cat needs to see the box move and understand where it is going. If you move it too fast or too far in one day, your cat may not find it and will have an accident elsewhere in the house.
Once the box is in the bathroom, position it next to the toilet. Leave it there for at least three to five days so your cat is comfortable using it in this new location. Watch for your cat using the box normally—if they are hesitant or having accidents outside the box, wait another week before moving forward.
Raise the litter box to toilet seat height over two to three weeks
Place the litter box on a sturdy platform (a wooden crate, storage box, or low shelf) next to the toilet. Raise it gradually—add a few inches every three to five days until the box is at the same height as the toilet seat. Your cat should be able to step from the step stool into the litter box without jumping or stretching.
This stage is where many cats get stuck. If your cat refuses to use the raised box or starts having accidents on the floor, lower it back down and wait another week. Some cats are nervous about height and need more time. There is no rush.
Once your cat is using the raised box consistently for at least one week, you can move the box closer to the toilet—a few inches at a time—until it is directly next to the seat.
Introduce the training seat with full litter inside
Place the training seat inside your toilet bowl with the litter pan filled to the same level as your cat's regular litter box. Leave the bathroom door open so your cat can explore. Do not force your cat to use it; let them investigate at their own pace.
Your cat may jump into the training seat right away, or they may ignore it for days. Both are normal. If your cat uses the training seat, praise them and leave it as is. If they avoid it and use the old litter box instead, keep both available for now. Some cats need a week or more to accept the new setup.
Once your cat is using the training seat regularly (at least five to seven days of consistent use), you can remove the old litter box from the bathroom. Keep it in another room in case your cat needs it, but do not put it back in the bathroom.
Gradually reduce litter and enlarge the hole over four to eight weeks
This is the longest stage and the one that requires the most patience. Every three to five days, remove a small amount of litter from the training seat pan—roughly a quarter of what was there before. Your cat will still have litter to dig in and cover waste, but less of it each time.
After two to three weeks of reducing litter, start making the hole in the center of the training seat pan larger. Most training seats come with removable inserts that create progressively bigger holes. Replace the insert with the next size up every three to five days. Your cat should still see and smell litter around the edges of the hole.
Watch for signs of stress: your cat avoiding the toilet, having accidents outside the bathroom, or straining to balance. If any of these happen, stop reducing litter or enlarging the hole. Go back to the previous step and stay there for another week or two. Stress-related accidents can become a long-term problem, so moving slowly is worth it.
Remove the training seat once the hole is nearly full-size
When the hole is large enough that only a thin ring of litter remains, your cat is almost ready for a regular toilet. Leave the training seat in place for another week so your cat is completely comfortable with the large hole and minimal litter.
Then remove the training seat entirely, leaving the toilet seat up. Some cats will use the toilet when ready; others need a few days to adjust. If your cat hesitates or has an accident, put the training seat back in for another week.
Once your cat is using the open toilet consistently, you can close the lid when the toilet is not in use. Your cat will learn to push it open or you can leave it propped slightly ajar. Some cats never fully adjust to pushing the lid, and that is fine—you can keep it open or partially open permanently.
Keep a litter box available as a backup
Even after your cat is toilet trained, keep a regular litter box in another room or in the bathroom. Some cats will always prefer the litter box for certain situations—stress, illness, or straightforward preference. A cat without a litter box option may hold waste, which causes health problems, or have accidents in closets and corners.
If your cat stops using the toilet and returns to the litter box, that is not failure. Your cat is telling you they are uncomfortable or stressed. Leave the litter box available and do not try to force toilet use again.
Frequently Asked Questions
What if my cat refuses to use the training seat?
Go back to the raised litter box next to the toilet and stay there for two to three more weeks. Some cats need longer to accept change. You can also try placing the training seat on the floor next to the toilet first, so your cat gets used to it without the height. Once they use it on the floor, gradually raise it.
Can kittens be toilet trained?
Kittens under one year old can learn, but they are less reliable because their bladder control is still developing. Wait until your cat is at least one year old and has been using a litter box consistently for several months. Adult cats learn faster and stick with it better.
Will toilet training hurt my cat's health?
Toilet training itself does not harm a healthy cat. However, if your cat becomes stressed or starts holding waste to avoid the toilet, that can cause urinary or digestive problems. If your cat shows signs of distress—straining, frequent trips to the toilet, or accidents—stop the training and return to a litter box.
What should I do if my cat has an accident outside the toilet?
Clean the spot thoroughly with an enzymatic cleaner so your cat does not smell their own waste there and return to it. Then move back one stage in the training process. If accidents keep happening, your cat may not be ready for toilet training, and that is okay. A litter box is a perfectly good solution.
How do I know if my cat is ready to stop using a litter box entirely?
Your cat should use the toilet consistently for at least two to three weeks without accidents before you remove the backup litter box. Even then, keep one available in a different room for at least another month. If your cat never asks for it, you can eventually remove it—but some cats will always want the option.
