This may sound ridiculous or like a near-impossible feat, but you'll find life is a pleasant new world when you finish potty training your cat. You'll have a very low-maintenance cat and she will also make a great conversation starter. And, you even save money on cat litter when you are done with potty training. If you want more detailed information than you'll find here on potty training, try a library or book store. In the mean time, I'll give you enough of a basic overview of cat toilet training that you probably won't need one of these books to successfully undertake potty training. The main thing you need to keep in mind as you go about cat toilet training is that cats require a lot of patience, with punishments being a very ineffective training method.
You will need to have a litter box, flushable cat litter, a bowl that fits inside your toilet,and a stool that stands approximately even with toilet. You will want to have your current litter box next to the toilet where you want your cat to potty for several days before you begin the process. This way she will get used to the location before you begin with potty training.
When you notice that your cat is consistently comfortably using the new box location, you can begin toilet training. To do this, simply move the litter box up about two inches by placing it on a phone book or other solid object, and start using the flushable litter at this point. After the cat has used the new location a few times, you can continue toilet training by putting the litter box on the stool up against the toilet. Make sure it is easy for the cat to get to this location and that the litter box is very firmly placed. Also, make sure the lid on the toilet seat is down. If the litter box ever dumps the cat during cat toilet training or she ever falls in the toilet, you may do irreversible damage to your cause.
After the cat has successfully used the new box location, your are again ready to proceed to the next step in the cat toilet training process. For this step, you want to place flushable litter in the bowl and put the bowl in the toilet. This is the trickiest part of the procedure, so be patient with your little friend at this point. You will want to leave this bowl here until your cat has reached the point in its cat toilet training that it is comfortable enough to use the bowl without having to step down into it. This will probably take the longest time of any of the procedures.
When the cat looks comfortable using the cat bowl inside the toilet, you're ready to proceed with potty training your cat once again. This time, you will remove the bowl so she will have only two choices: Continue going in the toilet or find a new place in the house to go. In most cases she will finish the cat toilet training process successfully by continuing to use the toilet. If not, you may want to put the bowl back in the toilet for a couple of days. Then, when you again remove the bowl, put the cat on the toilet five minutes after each meal and lock it in the bathroom for up to ten minutes. This should give your cat the general idea.
