Mercuri still missing

We let Mercuri out, as has been our ritual for the past few years, around 6 p.m. Thursday night. We called for her around 10 p.m., when she is usually nearby and ready to come in, but she was not around. This didn't worry us greatly, as she occasionally spends the night outside.

When we woke up Friday morning and she was not waiting at the door, that concerned us.

As of now, Monday afternoon, she is still missing. I'm hoping for the best, but preparing to not see her again.
