They had a device at the San Diego CAT SHOW last week where U can train your cat to use the POOT POOT seat instead of a litter box. IT starts out with some litter on the seat holder, and then after awhile, U take that piece out and the cat just squats and does what a cat has to do. HOWEVER, U wouldn't want the cat to use it as a drinking fountain if they learn to do this. Also, it is probably tough to teach the cat to FLUSH!
