friendly female young cat

A friendly stray female cat.
We took her home and she's been living with us for 2-3 weeks.
She's very friendly to people, and very confident.
Litter box trained, no accidents.
She warmed up to our other cats after several days and they get along.
Undetermined if she is fixed.
Surgical scar indicates maybe.
You can bring her back no questions asked if it doesn't work out.
