Maine coons and friends

[ddeaks]

I have a three year old ex breeding queen who we took as rehome 6 months ago. She has now been spayed but has had a least three litters. I am thinking of buying a kitten as company for Maisie , probably male Maine Coon. I wonder if anyone has any experience of similar situations and if this is likely to be a successful friendship? She does exhibit some 'mother' tendencies such as grooming me first thing in the morning !
