My sweetie got a box over him; I found a small sheet of plywood to slip under it (there was some delicate maneuvering to get all four feet+tail tucked in) and I carried him out and released him a few doors down. We hope he has neither trauma nor happy memories of our house.
We have him on video walking in like he owns the place - not a moment's hesitation - but when he and I noticed each other he suddenly became a LOT less confident.
I swear, we get better entertainment value out of the Blink cameras than any other streaming service. Neighborhood cats, raccoons, and now home-invading opossums - it's nonstop cabaret!
