He got really scared by the flash so I only have the one pic where he is in motion

I can't believe how friendly this thing is. It runs up the driveway every time I arrive, meowing like crazy. It's thin as hell and eating a ton.
It had a collar on, wrapped around its front leg really tight. It was there for so long that the flesh partially grew around it. It had to be cut off and now the skin is quite raw, but the cat is eating well and seems to have a lot of energy. It's all set up with a box and blanket to sleep in, I'm going to give it a day or two to see if a vet visit is necessary.
