Wanted: British Short Hair Female Wanted

Hello

I am looking for a purebred British shorthair female that is not too young, maybe 8 months to a year so that it can get along with my other female cat that is about 7 months old. If anyone has one for sale that is either white or golden in color with blue or green eyes that would be great 🙂
I don’t mind a little bit older than a year, but not too old please 🙂

Thank you
