SuperCat Next Door?

This morning, before leaving for work, I heard a noise outside our second-story bedroom window. Even though the weather has turned cold, I still haven't removed the window air conditioner. The seasonal temperature changes have to get fairly extreme before they get past my natural (supernatural?) resistance.

I looked to see what was causing the noise, and found our next door neighbor's cat. This cat is a young tomcat in a solid grey. It has a name, given by the neighbor, but around our house we call him Smoky or Thor. Well, there was Thor, clawing his way into our bedroom window.

How does a cat manage to get to a second-story window on a vertical wall? I'm wondering that myself. I might not be the only one on the block with special powers.

I'm going to have to keep an eye on that cat.
