Both my cats do this and I have absolutely no idea why - why do they suddenly get up after being asleep for ages and then zip from place to place - stop as if on a sixpence - then set off again. mine often roll as well and then suddenly - off again like they are on fire! It ceases as quick as it starts and the cat just walks over as if to say "that was good for me - how about you?"
They both drive me nuts when they do it!
