thankx
the bowl fits inside the toilet seat with edge catching the edge of the seat. I have been decreasing the litter amount for several weeks. i am getting ready to cut a small hole in the bottom but his scratching will push the litter in the toilet

if i can stick a little litter on the edge of the hole he won't be able waste it

as the days go by i make the hole bigger until he is doing the business right through the hole into the toilet

i just have to flush, no more litter

only side effect is the metal bowl has to be removed to use the toilet, no problem for me
