We have a similar railing in our house and Cot does the same thing. I try not to watch when he does as I just know he's going to fall(not)-even though he's a cat! I just know I would fall if I were trying to balance on a railing that narrow, lol! Good thing I don't try that! :)
hay @eliz do you notice one thing.............??????
He has two legs yes only two....... how amazing
