Dogs is different. Very few cats would like to be taken for walks on a lead down the pub, for example.
Dogs ain't different in that respect- its all in what the critters are trained to do. I've known plenty of cats who were just fine on a lead & WOULD have enjoyed awalk down to the pub.
By the way, how much do your neighbors appreciate the catshit & catpiss in their gardens? And why should they have to clean up after you?
