There has been a lot of discussion over the years about whether you can toilet train cat, dog or any other animal. The fact of the matter is, it is a relatively simple thing to do if you want to toilet train your cat. As far as getting your dog or other animal to go to the bathroom in the toilet, good luck with that. If you want your feline, however, to begin using the porcelain litter box then you need to start moving it in that direction slowly. Here's how you do it.
The first thing that you need to do is to move the litter box next to the toilet itself. This will get the cat used to its new area that will be going to the bathroom from now on. You also need to make sure that the seat is constantly down but the lid is always up on the toilet. If you have a man in the house that likes to leave the toilet seat up, he needs to be trained as well. If the seat is up, your cat will not be comfortable walking around on the porcelain rim and it's not very sanitary, anyway.
Every day, begin lifting the litter box up a little bit closer to the level of the toilet seat. You could probably add one or 2 inches to the height every day, just make sure that it is always stable as your cat will sometimes jump up into the box and the last thing you want to do is knock it over. It may take a couple of weeks, but eventually the box will be up as high as the toilet seat itself. Now it's time to move your cat over to the toilet.
You're either going to have to use a metal bowl that is the same size as the toilet bowl or fabricate a wooden box that will neatly fit down into the toilet area. Fill this box with litter and your cat will begin using it, just like it uses the litter box. Begin training the cat to keep its paws up on the seat and eventually, you will be able to remove the litter box from the toilet altogether. Your cat is now toilet trained and you can begin enjoying a litter box free house from this point forward.
