My cat runs up walls and swings upside down on chairs?

I think there's something wrong with him. LOL. He literally will jump and attack things that aren't there, wrap his arms around a door post and try to climb it (he has no claws) and he gets on the computer chair and hangs upside down on the arm rests. He makes these funny noises, and just goes berserk. It's like he's on crack or something. Does anyone else have a cat like that?

My kitten is JUST like this. I think it's just them being a little over excited. =P Sometimes my kitty will walk on two feet, and its CREEPY. Don't worry too much about it, some cat's are just..different. ^_^

Yes I had a female Siamese and a male Manx and both did that. If you have him neutered it will stop most of that.
