That's because nobody spent the time to train said cat. It's just like a dog. You have to put the time in to train the animal or of course it's going to shit/piss/destroy your stuff. 

We had a cat named Fred and he was trained like a dog. He would sit, fetch, go on car rides, follow you around with no leash and even obeyed the word "no". If Fred was on top of something he wasn't supposed to be we would just say no and he would jump right back down and not get up on that area again. 

Best cat ever. Could even make him attack things/people he listened so well. My uncle would visit sometimes and he was an alcoholic. Sometimes he would be belligerent talking trash to everyone and all we had to do is say "get em Fred" and Fred was on yo head gnawing a hole in your scalp.
