MChewk,
I have used 3/32” snare cable, frayed at the end, to retrieve both dead and live critters from confined spaces. Fray the end of the cable about 1”, insert cable into confined area, twist cable between your fingers; frayed end of cable will tangle in animal’s fur, pull animal from confined area. Use caution- some animals may be a little p----d off when they come out!
I learned this trick from my father in the 1940’s. He used barbed wire to recover raccoons and skunks that he had shot under deserted homes, outbuildings, and culverts. Barbed wire will still work too.
