How cute!! My Grandma had a cat who would do that. Of course, that cat like water. When we stayed with Gma the shower was in the basement. Gpa built it out of cinderblocks so the walls only went about 6 feet up. Pinky (her black cat who lived to 22 and climbed people like that) would get up on the wall around the shower and leap onto your shoulders. She even let me lather her up with shampoo and rinse her if I wanted.
I wonder how many people that cat has climbed? It was funny to see it on top of the officer's head.
