OK, so it takes him three months to do it, but - as cat pastimes go - it beats lolling on a windowsill or literally climbing the walls. Give him a year, he'd have 4 whole boxes dismantled for your green bin, productive little fecker. This industrious cat's progress is captured second by second and is nothing short of hypnotic. It's the visual equivalent of bursting bubblewrap, only better.
Well done, Elliot. You're playing a blinder for Mother Earth.
