Murderer

My name is Michele, and I'm a cat-murderer.

I ran over a cat today. No, it wasn't even a cat...kitten would actually be a better term to use. He was a pretty little black and white thing that came streaking across a yard and into the street so fast that I didn't have time to stop.

My question is this: what is the protocol in this situation? Because of his markings I could clearly see he didn't have on a collar, and we do have a lot of strays around. He was obviously completely dead. Should I have stopped? I honestly couldn't bear to. It will probably even be at least a week before I drive down that street.

I feel terrible, and I wish I could forget about it.
