Lyra's missing. Need ideas to find her

[Not Afraid]

Por girlie. She REALLY wants to go back outside. I'm thinking it may be her time and she's looking for a place to die. It may be time to take her for her last vet trip.

I wish there was a little colored coded marker - like a pregnancy test - that would tell me what is the humane things to do. White, she's ok, Blue, she's miserable and it's time. But, no such luck.
