We saw our cat walking down the down pipe onto tank from the roof,then across the tank ,down the vine hanging over the fence which went down to the ground next door but she go off when she reached the fence & walked back along the fence until she reached the retaining wall & jumped off.

I didn't go inside to get the camera because I just wanted to watch her ,to see how she got up there in the first place.See Photos 1 & 2.
