I don't think ocelots can legally be kept as pets anymore, but they do easily adapt to using a toilet. In the wild, they climb a tree overhanging a stream or river to do #2. So toilets are pretty much second nature to them. http://www.cathouse-fcc.org/peaches.html

While I have never seen these products before, I have trained cats to open the bathroom door, turn the light on, use the toilet, flush, turn the light off, and close the bathroom door on their way out ... All I had to do was replace the round door knobs with with a 6" long crescent lever handle that a cat can easily jump up and pull down on, replace the tiny light switch with left (on) & right (off) 2" square buttons that can be tapped easily, and replace the flush control with a longer lever flush handle ... then teach the cat to use them ... starting at about 3 months old, it took about 5 to 6 weeks for the kitten/cat to get everything perfect ...

I would only do that if my cat were a Bengal tiger.

Only then would the cat's butt fit on the toilet seat.

I did have a cat many years ago, Elvira, that would use the toilet if we left the seat up. We did not train her to do it, she did it on her own.
