Yeah I've been looking on you tube to see people training their cats to go in the potty and I'm thinking that I rather not push my cat(s) to learn that since I think I wouldn't be happy if someone tried to get me to abandon my instinct. Its cool Idea if your thinking green, but I also think if my guest came in and saw my cat using the potty they might not want to go in our bathroom b/c of some "sanitation" issue. You know how people can get about cats but when dogs drink out of the toilet and leave a dripping mess on the seat its not an issue. Though our family is more old fashion and we don't have issues with our pets drinking out of our toilets it be weird to see them using them.
