I have a friend who does tend to go overboard on the animal rescue thing. She always has a menagerie at home, and absolutely cannot pass a dog or cat on the street without trying to find out who owns it and get it home. It pains me to see a homeless animal to, but to her it's almost like it's a personal affront that she can't leave alone. I remember once she and her boyfriend were somewhere in the northeast (MA, CT, ME, somewhere that I don't remember) on a trip. They were going through a residential area about 10:00 at night and she saw a dog walking down the street. She stopped, got the dog, started knocking on doors until she found the owner, and then read them the riot act for not keeping their dog up at night. There is a limit to what can be done, but she doesn't recognize it.
