That cat has the look of 'You've come close enough. Back off or things will get ugly.' and also, 'I can totally outrun you.' all over his face.

I see that same look every time a new stray shows up. I think I've only ever had one who didn't learn he could trust me.

Balboa came around pretty quickly. He's at the point now where he jumps up into my lap and purrs while making bread. He's got extra toes, so it's extra OW! Quit it!

Of course, this guy used to have a home, he was dumped and incredibly stressed and disoriented when he found me.
