Well, when I was putting them up there tonight he jumped up on the ledge and I thought "Wow, that's a weird reflection of Presto in the window." Then I realized it wasn't a reflection. I looked again and thought it was a big dog hanging out in our backyard.
As I started to move closer to the window to look it leapt about 4 feet in the air and bounded away.
Dogs don't bound...especially when they are startled. But you know what do??
