When I was a kid, I guess mom heard something under the house in the crawlspace. She thought it was a cat, so went under with a knife and flashlight. She came across a hissing possum! She chased it around a while and scurried out and said "That is no kitty cat!" She asked dad for his .44, but he thought that unwise. We left the access panel loose and heard it knock it over and find a more peaceful home.
