Sampson

Or perhaps Simon. The collar just says "I am not a stray" which doesn't answer the question. (He's left several collars in our yard, after snagging 'em on bushes.)

Sampson/Simon lives a couple doors down, and imagines himself the king of the neighborhood. The problem with the theory is that he needs to get around the cats in the yard between ours and his--and he's quite afraid of those cats. Makes for some interesting dynamics.

He was stalking birds in our yard this morning when I took this photo. I chased him home.
