Need some help up here?

Our house is still torn up due to our recent project, and our cats have been going crazy. We had to take Jordy to Grandma's house (thanks again!) and Willie has been locked up in the basement or garage. Willie has finally been freed the past few days and he is enjoying his freedom. Last night when my roommate and I were moving furniture we heard a weird noise. We look around the corner and Mr. Willie has climbed up the ladder. I don't know how he really did it, but seriously, nothing surprises me with this cat!
