After adding bowls of water to a mock toilet filled with LOTS of litter, a cat will put 4-paws up on the seat, figure out how to aim into the water, realize water covers stench better than litter, and finally switch to the real toilet. Remember, stress-free is the key to accident-free.


1 Sitz Bath

Sitz Bath

2 identical, traction-friendly toilet seats (3 inches wide is standard in the USA)

Soft, Non-slip Toilet Seat (3" wide)

1 heavy-plastic storage container with a thick, secure lid (12 inches tall) (fill with bricks to stabilize)

Storage Container

1 soldering iron (use outdoors) OR 1 box-cutter utility knife OR 1 pruning shears (a dremel may also work well)

pruning shears


Soldering Iron

9 containers in graduated sizes (from test-tube to deep mixing bowl)

Water Containers


1. Using the soldering iron (outside), box cutters, or pruning shears, cut a hole in the lid of the storage container. The size of your hole depends on the size of the sitz bath. You want the sitz bath to hang securely in the hole.

2. The sitz bath has several raised portions that won’t allow the toilet seat to close properly. Using the pruning shears, cut them out. Duct tape over the holes in the sitz bath where litter might escape.

3. Using the soldering iron, melt two tiny holes in the lid of the storage container. These holes correspond to the size and positioning of the toilet seat bolts. The toilet seat sits atop the sitz bath, secured by bolts to the lid.

4. Assemble. Add weight inside, so the cat(s) don’t tip it over as they launch to and from the mock toilet.

5. Put the second toilet seat on the real toilet. It’s very important to have identical training seats on your mock toilet and the toilet you expect your cat to adopt. Add 4-6 inches of litter and begin training.

6. For the last two steps of training, get out the soldering iron and cut a hole in the sitz bath, so you can hang a deeper bowl in the setup (more toilet-like).


1. If after your best efforts, the setup isn’t entirely secure, grab a roll of duct tape and make it so. Duct tape is also handy for covering up the openings at the top of the sitz bath (where the cords are meant to feed through, if you’re using it for humans).

2. If training a kitten, keep the real toilet lid down until the kitten is sure-footed enough to have absolutely no danger of slipping or accidentally jumping into the bowl. Kittens should be 11-weeks old before training is started.

2. If training a sure-footed feline, tape the real toilet lid to the tank in the open position. You don’t want the lid falling on the cat, causing water phobia.
