A cat training seat is a small contraption placed over the toilet bowl. A small indent in the center of the device will be filled with flushable litter. As you progress in training, you begin by cutting bigger and bigger holes in the training seat until your cat gets used to urinating and defecating straight into the toilet rather than litter. You can purchase a training seat or make one on your own. [2] X Research source The City Kitty Cat Toilet Training Kit is one such training seat. The seat has four rings that can be removed to increase the size of the hole in its center. At the trainings completion you remove the tray altogether. CitiKitty is a simple device that is inexpensive. It generally sells for $30. [3] X Research source The Litter Kwitter is another brand of training seat. It has color coordinated training trays of increasing size. As your cat progresses in training, you will swap out a larger tray for a smaller one. Eventually, you’ll be able to move the tray altogether and your cat will eliminate straight into the toilet. The Litter Kwitter is highly convenient but can be somewhat expensive. It generally sells for $40 to $50. [4] X Research source If you’d rather save money, you can create a training tray yourself. You will need duct tape, plastic liner or kitchen plastic wrap, and an aluminum roasting pan size 12 5/8" x 10 1/8" x 3". [5] X Research source

To create the training tray, simply place the aluminum roasting pan over the toilet’s rim. Secure in place with duct tape. [6] X Research source If the tray is not big enough to fully encompass the toilet bowl, fill in any gaps with plastic wrap. [7] X Research source

If you’re using the Litter Kwitter or a similar product, use the smallest training pan. This training pan will have no hole in it and you’ll simply fill it with flushable litter. [10] X Research source If you’re using an aluminum tray, simply put the tray in place and fill it with flushable litter. Do not cut any holes in the tray yet. [11] X Research source

If you’re using the Litter Kwitter or a similar product, gradually transition into bigger and bigger training seats. Training seats will have small holes in them that get larger as your cat moves through his training. If you’re using an aluminum, use a screw driver to cut a hole in the bottom of the pan. Every day, make the hole slightly bigger. [12] X Research source Gradually decrease the amount of litter you’re using as well. Each time your cat eliminates in the pan, replace the litter with a slightly smaller amount than before. [13] X Research source

If your cat is very young, less than six months old, or already has issues using a litter box, toilet training might not be the best option. Cats who are older and are already comfortable with their litter box are easiest to toilet train. [15] X Research source If your cat is skittish, he might struggle with litter box training. Shyer cats generally prefer to cover their feces and urine to protect themselves from potential predators. [16] X Research source Toilet training takes time, organization, and dedication. If you’re not generally a well organized person or if you’re very busy, you might be better off sticking with litter. [17] X Research source

First off, toilet training goes against a cat’s natural instincts. Cats have a natural tendency to dig and bury when eliminating. Using the toilet, even after proper training, can cause stress for a cat. You do not want using the bathroom to be a stressful event as it can lead to behavioral and health issues for your cat. [18] X Research source The toilet lid must always be left open. If you or a house guest accidentally closes the toilet lid, your cat will eliminate elsewhere. [19] X Research source Older cats or cats with joint problems will have trouble reaching the toilet and maintaining balance on the rim. There is a risk for injury with toilet training, especially for senior cats. [20] X Research source
