That's what makes them so cool, provided you don't get on their bad side. They're like wild animals. I'll take a wild animal that I don't have to baby-sit over a proper pet any day. They do get annoying when they're hungry, though...
That's true. I was watching a show on the discovery channel with my nephew, and it showed how they are domesticated, but still have the same predator instinct as their wild counterparts. I think the show was the top ten predators, and the housecat was number one, LOL! They had slow mo action footage of them crouching and pouncing looking all fierce, lol.
