Toilet trained cats.....
There are 2 possible outcomes.
1. It doesn't work, and you end up with cat poop where the litter box used to be, and every morning when you go to take a shower you get litter on your feet until your girlfriends' roommate who owns the condo where you're living finally gives up and takes the freaking thing away, by which time the cat has learned to poop in lots of places like your shoes, and the cat continues to do that until you finally have to marry your girlfriend and buy your own house.
2. It works, which is the same as (1) except for now everytime you have to go you have to deal with cat poop, and if you think it's fun living with 3 women and having to put the seat down try it with having to not only put the seat down and put the stupid training device and its litter back on the toilet, but now you have to _wait for the cat to finish_ before you can go, at which time pissing in one of the plants starts to look like a viable option.
Also note: Cats can't aim.
