ABOUT
OUR UNWAVING COMMITMENT TO QUALITY
We are proud to uphold the highest standards in ethical breeding, delivering exceptional kittens that exceed expectations. Through an exclusive agreement with Marcy Ciriello of Of True Diamond Switzerland, we are honored to represent her elite bloodlines in the USA.
As the first U.S. cat club affiliated with Federación Felina de México (FFM) under FIFe, we celebrate a historic milestone in the world of pedigreed cats-driven by passion, integrity, and excellence.
Founded in 2019, Of True Diamond Switzerland is globally recognized for producing kittens of rare type, exceptional health, and ideal temperament. Behind it is Marcy, a breeder with over 30 years of experience in the animal world-including work as a licensed FCI dog breeder, professional trainer, handler, and groomer. At the age of 19 years old she had her first litter and spent over a decade in Spain working as a volunteer in The Animal Protection Agency of Spain, gaining deep expertise in welfare, genetics, and nutrition.
Her kittens are celebrated for their structure, coat quality extreme ear size and positioning, consistently earning top titles and recognition across Europe. Marcy has taken advice from FIFe judges and continues to refine her kittens to better meet the FIFe standards of excellence.
With Marcy as our mentor, we aim to build upon this legacy by refining our lines with a sharp focus on health, structure, quality, and beauty, all while upholding the high standards established by FIFe.
FOR EVERY KITTED ADOPTED
WE DONATE TO AN ANIMAL CHARITY
At Of true Diamond USA, our purpose goes beyond breeding extraordinary Devon Rex cats-we are devoted to making a meaningful impact in the world, one pawprint at a time. Through our Purpose with Heart program, we pledge a portion of every kitten adoption toward causes that reflect our core values: compassion, care, and community.
With every kitten placed, a gift is given.
Our contributions support:
- FIP research and feline health initiatives
- Rescue and rehabilitation of vulnerable cats
- Educational programs promoting ethical breeding and responsible pet ownership
This initiative is our promise to give back-to both the feline world and the families who open their hearts to our kittens.
Because when you welcome a True Diamond kitten into your home, you’re not just receiving a beautiful companion-you’re joining a movement built on love, integrity, and purpose.
