cool vid.
when mine was younger (much younger lol) i'd stand at the bottom of the stairs and he would go to the top of the stairs - i'd toss a ball or a toy up in the air over his head - he'd leap in the air, snag it, put it down on the ground, and then knock it down the stairs to me so i could throw it to him again.
he's unusually bright though, i think - he also figured out how he could escape to the outside, when he was alone in the room he started unthreading the screen window from its frame, piece by piece, like a prisoner chipping away at the cell doors - he was really pissed when I discovered him before enough of the screen had been unthreaded to let him out. so then he started begging to play in the basement - it turned out that he'd found a window in the basement that wasn't locked, and that he could wedge through it to get out; after a few hours he'd come back inside and bang at the basement door to come upstairs. it took me almost a year to accidentally "bump into him" outside and his game was up
he's almost 17 now, so these days he'd rather just sleep
