teaching a cat how to use to toilet

I think that certain cat breeds are better at learning this than others. Ocelots (which, of course, aren't domestic cats), apparently prefer to defecate in running water naturally and when kept as pets understand the principle of the flush toilet pretty quickly. Apparently, domestic cats can be trained by taking the process in slow stages, starting with moving the litter box next to the toilet, then raising the height of it every few days and finally by putting the litter box ON the toilet seat with a hole cut in the bottom which you increase in size gradually until the cat gets the idea and the litter box can be dispensed with. All of this, of course, is likely to take several weeks and a lot of patience! This site is devoted to the subject of toilet training cats and has a lot of information (as well as wanting to sell you special equipment, of course, which is not strictly necessary!):
