Trouble the tomcat leaps onto the upstairs stair railing and paces back and forth sometimes. I have no idea how he does it but he has no fear of heights and seems to enjoy walking back and forth on a railing barely an inch or so wide. I watch him leap upon it where it's the greatest distance to fall but his balance and four paws don't let that happen. I tried to snag a photo of him walking along the ledge but was only able to catch him stepping off it tonight.
At he same time Shiloh was snuggled in my recliner. She has never tried to walk the railing and I believe she thinks her brother is nuts for doing it.
