Just a mess: all skin & bones, no teeth, older lady soaking wet in the rain. The cat yelled and followed her and then literally laid down at her feet. My wife scooped her up and carried her home.
We took her to the vet, tentatively named her Anchovy. Too freaked out and thin to get much in the way of tests or treatment yet.
We set her up in our garage in a blanket-wrapped carrier with a space heater on low. Been feeding her a little wet food every few hours, which she gobbled up eagerly. Trying to be careful not to over-feed for fear of refeeding syndrome.
Over the weekend, she warmed up and dried off. Been eating & drinking well. Gave her a litter box, which she's using no problem. She very clearly wants attention and company. Got another vet appointment this coming weekend, hopefully we can put a little weight on her.
