Hobby, ok, maybe in Australia you need to start some re-education programme for your cats. I am sorry, though, it won't work. They'll keep behaving their way, using your clean streets as their personal toilets, feeling quite happy about it. Face it. Maybe you could exterminate them all, to solve the problem. That is, if you think it's a good idea.
About Italian dogs: yes, they're different. They carry guns and kill people, occasionally acting as hitmen (oops, hitdogs). Italian dogs are mafiosi, and of course so are Italians, which explains precisely why we like to keep our dogs subjugated.
