Litter Kwitter Cat Toilet Training System

i started this in march and i hate it to death. this has been the most disgusting experience i've ever had to endure. i seriously want my money back.not only are the discs hard to clean due to pee getting in between the disc and the potty seat that goes on the toilet... but the discs arent deep enough so the cats end up kicking litter all over the place.. which means litter is all over the bathroom floor and being tracked all over the house, i cant even keep my bath mats on the bathroom floor and i have to always make sure i'm wearing sneakers or slippers when i enter the bathroom.at first it seemed like my cats were going to be successfully potty trained... but when i moved to the orange disc, they only went on the potty once in a while. so i kept putting them on the seat and it seemed like they were back in the habit of using the potty again. eventually i moved on the the green disc and both cats have completely STOPPED COLD FREAKIN TURKEY... which means my house STINKS to high hell because they are peeing and pooping all over the damn place!i keep putting them on the potty, but they refuse. i'm thinking the holes are too big and maybe they're afraid of the water. i'm actually cleaning up more poop now than when i had a litter box... which i'm going to have to buy later today because this is just ridiculous. i hate this product. if i could give it ZERO stars, i would
