Cats can learn to use the toilet instead of a litter box, but it takes patience and the right setup
Yes, potty training a cat is possible. Many cats can learn to use a toilet or a special training seat instead of a traditional litter box. The process works because cats are naturally inclined to bury their waste—they already have the instinct. What you are doing is redirecting that instinct from litter to the toilet.
The training typically takes between two and six months, depending on your cat's age, temperament, and how consistently you follow the steps. Kittens and younger cats usually learn faster than older cats. Some cats take to it when ready; others need more time. The key is moving slowly through each stage and not rushing your cat forward before they are ready.
Key Takeaways
- Potty training a cat works best when you move gradually from a litter box to a training seat to the toilet over weeks or months.
- You will need a toilet training kit (a seat that fits over your toilet with flushable litter or pellets) to start the process safely.
- Some cats refuse to use the toilet and prefer a litter box, and forcing the issue can cause stress or inappropriate elimination elsewhere in your home.
- Older cats, cats with mobility issues, and cats with medical conditions may not be good candidates for toilet training.
- Even after successful training, you should keep a litter box available as a backup in case your cat has an accident or refuses to use the toilet.
What you need before you start
A toilet training kit is the main tool. These kits include a seat that fits over your toilet bowl and a series of removable trays with increasingly larger holes. Popular brands include CitiKitty, Litter Kwitter, and Potty Training Kit for Cats. The seat stays in place, and you gradually reduce the litter in the tray and enlarge the hole over several weeks so your cat gets used to balancing on the toilet rim.
You will also need flushable litter or pellets designed for toilet training—regular clay litter clogs pipes. Some kits come with pellets included; others require you to buy them separately. Check what your kit recommends before you start.
Keep your regular litter box available during training. Your cat needs a backup, and having two boxes reduces stress if your cat is uncertain about the new setup.
The step-by-step process
Week 1 to 2: Move the litter box next to the toilet. Let your cat use the box in its new location for several days so they become comfortable with the bathroom as their toilet space. This is the easiest step and usually causes no problems.
Week 2 to 3: Gradually raise the litter box. Place the box on a low stool or platform next to the toilet, then slowly raise it over a week or two until it is at toilet height. Your cat learns to jump up to use the toilet. Move the box closer to the toilet each day.
Week 3 to 4: Place the training seat on the toilet. Put the training kit on the toilet with the first tray (the one with the smallest hole) in place. Move the litter box away. Put a small amount of flushable litter in the tray so your cat recognizes it as a toilet. Some cats use it when ready; others need a few days to adjust. Stay patient.
Week 4 to 8: Gradually enlarge the hole. Most kits have three to five trays with progressively larger holes. Move to the next tray every one to two weeks, but only after your cat is consistently using the current one without accidents. If your cat stops using the toilet or seems stressed, go back to the previous tray for another week.
Week 8 to 12: Remove the training seat. Once your cat is comfortable with the largest hole, remove the training kit entirely. Your cat now uses the toilet directly. Some cats need a few days to adjust to the open bowl; others transition when ready.
Signs your cat is ready to move to the next stage
Your cat should be using the current setup consistently—at least five to seven days without accidents—before you move forward. If your cat is hesitant, missing the hole, or eliminating outside the box, stay at that stage longer. Rushing causes stress and often leads to litter box avoidance, which means your cat will eliminate in closets, under beds, or other places in your home.
Watch for signs of stress: excessive meowing, reluctance to enter the bathroom, or straining. If you see these, slow down or consult your veterinarian. Some cats are straightforward not suited to toilet training, and that is normal.
Cats that should not be potty trained
Older cats (over 10 years old) often struggle with the balance and coordination required. Cats with arthritis, hip dysplasia, or other mobility issues may find jumping to toilet height painful. Cats with medical conditions like diabetes, hyperthyroidism, or urinary tract disease need straightforward access to a litter box so you can monitor their output—a toilet makes that impossible.
Kittens under four months old are usually too small and uncoordinated. Cats with a history of litter box avoidance or behavioral issues may become more stressed by the change. If your cat has any of these characteristics, a traditional litter box is the safer choice.
Common problems and how to fix them
Your cat refuses to use the training seat. This is the most common issue. Go back to the previous stage for another week or two. Some cats need more time. If your cat avoids the bathroom entirely, remove the training kit and return to a regular litter box for a few weeks before trying again. Never force your cat to use the toilet.
Your cat is having accidents outside the box. This usually means you moved too fast. Return to the previous tray size and stay there longer. Also check that the training seat is stable and not wobbling—an unstable seat frightens cats. Make sure the seat is clean; cats are sensitive to smell.
Your cat uses the toilet but splashes or misses. This is normal during the learning phase. Place a mat under the toilet to catch splashes. Some cats never achieve perfect aim, and that is acceptable. If splashing is severe, you may need to keep a litter box as a permanent backup.
Your cat was trained but stopped using the toilet. Medical issues are the first suspect—urinary tract infections, kidney disease, and digestive problems can cause cats to avoid the toilet. See your veterinarian. If your cat is healthy, stress or a change in routine may have caused regression. Return to an earlier stage of training and move forward more slowly.
What to do after your cat is trained
Keep a litter box available, even after successful training. Some cats regress, and having a backup prevents accidents throughout your home. Place it in a different bathroom or a quiet corner so your cat has options.
You will still need to clean the toilet regularly. Urine and feces can accumulate on the rim and inside the bowl. Flush after each use and scrub weekly with a toilet brush and cleaner. Some people place a mat or seat cover on the toilet when not in use to prevent splashing and keep the bathroom cleaner.
If your cat ever stops using the toilet consistently, return to a litter box without frustration. Toilet training is a convenience for you, not a necessity for your cat. A litter box is always the safer, less stressful option if your cat shows any resistance.
Frequently Asked Questions
How old should my cat be before I start potty training?
Most cats are ready between four and six months old, when they have better coordination and bladder control. Younger kittens lack the physical development. Older cats can learn, but cats over ten years old often struggle with balance. The best age is between one and seven years old.
Will potty training hurt my cat or cause health problems?
Toilet training itself does not cause health problems if done gradually and without forcing. However, it does prevent you from monitoring your cat's urine and stool, which can delay diagnosis of kidney disease, diabetes, or digestive issues. If your cat has any medical condition, a litter box is safer because it lets you track changes.
What if my cat refuses to use the toilet no matter how long I wait?
Some cats straightforward prefer a litter box, and that is fine. There is no benefit to forcing the issue. Return to a regular litter box without guilt. Your cat's comfort and stress level matter more than toilet training.
Can I use regular litter in the training kit?
No. Regular clay litter will clog your pipes and cause expensive plumbing damage. Use only flushable litter or pellets designed for toilet training. Even then, some plumbers recommend not flushing anything and disposing of pellets in the trash instead.
Do I still need to clean the litter box if my cat is toilet trained?
If you keep a backup litter box (which you should), yes—clean it daily just as you would normally. If your cat stops using the toilet and returns to the box, you need it ready and clean to prevent accidents elsewhere in your home.
