We had a pump action BB pistol for the raccoons in Marin, there was a whole family living in my neighbors crawl space. They'd already cost me $300 in vet bills for my cat. So, one night Mimi pumps that gun up as far as it would go, about 18 -20 pumps and pops the big male in the rear. He stands us, grabs his butt, looks up and charged at Mimi! She came running back in the house so fast. I was trying not to laugh my head off. Eventually we went over and repaired the window they were using to get under the neighbors house, she just couldn't handle it. It took a lot of nights with the BB gun and after that Mimi stayed right by the door. Eventually, the pups grew up and they all seemed to move back into the park behind us.
