I am so sorry about your cat. And I know that you true very hard with all your strays. Unfortunately one person can't save them all, but you are doing boatloads more then some people to help them! Me included!
This woman would definatley try my patience. I can't even imagine how angry you are. My solution would be to install ranch/cattle type fencing. So at least she would have to stop to go thru. I don't know what keeps you from clawing her eyes out!
The blatant disrespect for people and animals is what would get me. Too bad you can't have someone shoot her tires out as she is flying up and down the lane!! Oh wait!!! Don't repeat that - That IS ILLEGAL!!!
