Found a kitten, not chipped. What do I do with it?

For the past 4 days I’ve had a cat outside my door meowing/screaming non-stop.

I initially ignored it because I thought it was someone’s and potentially in heat, but today I finally ended up taking it to an emergency vet, since she’s been here for days and not attempting to return home.

1. She’s 4-6 months old according to the vet.

2. Not microchipped.

3. Well taken care of, doesn’t seem like a stray.

4. Full of fleas and ticks.

5. She’s super friendly and affectionate.

I live in the middle of nowhere type of village, and went around all my neighbours to ask if they know who she is, but nobody does.

She’s been permanently either under my car or inside a bush next to my house, screaming non-stop in distress.

I don’t mind taking her in, but I’m worried someone may be looking for her. I was unable to find anything on lost pet Facebook groups or even on a local board. What do?
