I have seen my Jumper (part Abyssinian kitten) act up whenever he wants attention. You know, abys get into things and scoop them off the shelves and make lots of noise. Jumper not only does this but also he stars meowing (aby style). So, I have to drop what I'm doing and pick him up for some cuddling, and this takes care of the situation. I'm thinking that your cat may be bored or lonley or perhaps even hungry. But some of them can get aggressive at times, which is also a sign of a healthy kitty. I had only one large male cat several years ago, who would attack my feet whenever I walked by him, and this was because he was hungry. After feeding him, the aggression stopped.
