Well. Shadow got out by levering you a window I’d left cracked open for fresh air for both of us. With the cone.
We chased her around and ultimately coaxed her out from under the house two doors down, took the cone off, and told her she was a free cat again. She’s not fully healed, but I think she has made it clear she is Done with being captive in a house that’s barely set up for humans, let alone cats.
She has probably already scratched off the scab. Hopefully the antibiotic shot combined with it being closed a lot further than it would have without a few days of cone will mean it heals up okay.
