On other BYC threads people who have tried to re-home wild critters in the interest of preserving wildlife had critters cleverly return or become another neighborhood's problem -- so the uniform advice has been overwhelming to destroy the pests when captured. Bleeding hearts will deem this cruel, however the Possum & Coon are not endangered and their populations are out of control. Japan has an eradication program to rid their non-indigenous feral population of imported USA Raccoons because of the destruction to Japan's historical temples and monuments. Once the imported Coons in the 1970's became unmanageable as adults the Japanese owners released the pets into the forests where they multiplied out of control.
I love wildlife but I also have a responsibility to my family, domesticated animals, and private property to protect them from intrusive or even dangerous wild critters. Possums & Coons are not just destructive aggressive hunters for food but are downright challenging toward humans as well and that's not to mention the possibility that they carry rabies, ticks, etc. I would never confront one face to face unless it was securely caged or I had a reliable weapon. One can never know if a Coon will attack you - especially if it is rabid or is a female that has half a dozen kits hiding somewhere in the vicinity.
The city populations of Coons is so great that these normally nocturnal predators are being sighted during daylight hours. We and our neighbors never thought we had Coons until I spotted one diving into our street's storm drain late one evening! Those were not loud cat paws we were hearing on our roof at night! We and all our neighbors have cut down our old, tall, or dying trees to eliminate the convenience for squirrels, rats, possums, or raccoons using them to jump conveniently from yard to yard. We've also made a concerted effort to clean out wood piles and storage sheds and move our trash bins away from areas where we don't want wild critters. We don't leave any chicken feeders/waterers outside overnight either.
