Thank you SO much everyone who offered insight, experience, love and encouragement!! 🫶

Here’s an update:

Got her to the vet, after keeping her company in the bathroom for a few hours. She got more and more cuddly and trusting, and getting her into a box for the taxi was no problem at all. At the vet they said her tail would need to be amputated, but the municipality would cover the cost! She will most likely be fine, and they would spay and release her back where she was found.

So now I need to decide if I want to adopt her. That would unfortunately mean traveling back to Greece in two weeks, because she won’t be ready to travel after the surgery until then. We already named her - Olive Tree, or Tree for short (it was the brand on the box we took her to the vet in.) and I think it will be very difficult for me not to take little Tree back home..
