Mainastasia is a small in-home cattery.  We  live in O'Fallon, Missouri, which is located about 30 minutes from downtown St. Louis and the famous "Gateway Arch".  We have been breeding and showing Maine Coons since 1999.     We strive to breed healthy Maine Coon's with gentle, loving and sweet personalities.

Our breeding cats are screened for Hypertrophic Cardiomyopathy  (HCM) annually.

In addition to having yearly ultrasound color flow Doppler screenings performed by a veterinary cardiologist, all of our breeding cats have tested negative for the MyBPC Mutation that was recently discovered by Dr. Kathryn Meurs, DVM.

More information about this mutation can be found here.

Disclaimer:  Screening our Maine Coons for HCM and FHD is currently the recommended method to aid in reducing the incidence of these genetic conditions in our cats.  Breeders  cannot guarantee that their cats will not have either of these conditions, however, Mainastasia can guarantee that we are dedicated to screening our breeding stock in a continued effort to produce healthy and sound Maine Coon cats to the best of our ability.

We are breeder members of the Maine Coon Breeders and Fanciers Association, (MCBFA)      

Our cattery is registered with both the Cat Fanciers Association (CFA) and The International Cat Association (TICA).

Our cattery is in our home where our breeding cats are our pets first.  Our kittens go only to approved indoor only homes and with a no-declaw agreement.

Please take time now to view our Contract  and our  Health Warranty which must be signed before receiving a kitten from us.
