As those of us with cats can attest, these little beasties seem to love computers. Be it for somewhere to lay on top of, rub against, meow at, or bat at the screen. In the last few months, a fair number of macs have come into my house. My cats seem to love iMacs (everything from the tray load to the latest intel iMac) and the aluminum PowerBooks more than any other machine Apple's made. They don't seem to care much for the plastic PowerBooks (1xx-G3) or any of the iBooks. The only way for me to use a computer without a kittie trying to cuddle with it, is by using a PowerBook other than my 15" aluminum. They just love to lay on the keyboard/trackpad more than anything.
