Since K&L are on vacation this week, I can "sort" of answer your questions.

Their Vet knows what they do and works with them, usually giving them a price break and doing special favors for them. They also work closely with a few organizations who TNR, this helps a whole lot!! Also a lot comes from their pocket.

If you are interested in TNR you should check your local phone book. I do know there are websites out there, but I do not know them. I'm sure the other's on this board will help out.
