When I first reentered society I had to live in a BS trailer park-they used to put bounties out on feral cats as they'd crawl under the trailers and scratch their way into your home. I once had to kill a HUGE possum using a steak knife and a baseball bat . when angry (or in it's death throes) Possums show their second set of razor sharp teeth -kinda looks like a 25 lb rat.
