Apparently it is relatively easy to teach cats to use the toilet. You can buy a kit online that, in stages, takes the cat from the litter tray to the toilet using different sizes of toilet seat attachments.
Toilet training kits can be purchased on the web or at a pet store. Young cats are interested in toilets. Toilet training a young cat should be easy to do.
Place a litter box in the toilet, show kitty the litter, once she starts useing it there remove the litter and kitty should continue to go on the toilet.
