Tobi is bell and litter boxed trained. I have read the posts and some say they miss the pad or have an accident due to owner fault, Tobi misses his box sometimes when he goes finish up (poop). He rings his bell for the same reasons as mentioned, to go out and pee, to see what is going on outside, just being nosey. I thought I would never get him this trained....it is great, however, due to his chewing and scratching, he is stays in his house while we are at work. He is a great boy and I love him to pieces!!
