Local cat owner with just one young kitten? I have one.... (rohnert pk / cotati)

I found a stray 4 week old very healthy and super friendly kitten. I have 4 cats or I would take her. She is super sweet/well adjusted/never spooked easily etc etc Love to find a kitten playmate/lifelong partner for her. Please be semi close to Rohnert Park so I can maybe visit her.
