Bei Bei's milestone for today was to climb up to the top of the mountain and put both paws up on the window ledge (he was up on his tippi toes at one point). He spent quite a bit of time up there investigating the wall. Then, as with the other day, the trip down was a bit tougher. (Video feed was very jerky at times).
