Best of luck for you and Fraidy
If they can release her back here (I’m not optimistic), we’ll offer to let them release her on our deck or in our backyard because it’s a place she knows. I’m not sure they’d do it, but we can offer. My gut tells me she’ll most likely be put down, though, because I believe that is Fairfax County’s normal policy for injured or sick feral or “community” cats.
