Has anyone notified the police? I don't know what area you are in, but it is possible that firing a pellet gun is against local ordinances. We had such a case here in my city this past summer. I think the police need to know as well as the animal rescue groups. Oh, and I am wondering if the vet has to report it when you take the cat in for his foot. Ya know, like they have to report dog bites in some areas.

I vote that you get in any and all cats that you can ASAP. It may take a week or 2 or 3, but PT will come through and help you, I don't doubt that!!!! Count me in for help as soon as you get things established. I'll be watching this thread.
