Welcome! We are Trish and John, and thank you for visiting Giant Gems Maine Coon Cattery website. It’s been pure joy sharing our home in Western Michigan (USA) with these incredible Maine Coon cats. When we founded Giant Gems Cattery, our mission was clear: to breed the finest purebred Championship European Maine Coon kittens anywhere—ones with unbeatable beauty (championship bloodlines), temperament, personality, and, above all, rock-solid health and wellness.
Health is non-negotiable for any responsible Maine Coon breeder—no exceptions! A quick dive into the breed’s challenges shows why. That’s why we’ve crafted one of the nation’s most comprehensive Breeder Support Programs for adoptive families. Guarantees alone fall short; true success demands our “Best Practices + Best Advice + Best Guarantees” trifecta for a lifetime of healthy, happy memories with your new Maine Coon Fuzz Nugget.
We start with rigorous testing on all our champion breeder cats: perfect DNA genetics, flawless hearts (via echocardiograms), and superior hips (via dysplasia x-rays). From there, we guide you with proven protocols for vaccinations, exams, treatments, procedures, and even stress management to minimize FIP risks. Backed by LIFETIME Support/Advice Service, a 5-Year DNA Genetic Health Guarantee, and a 1-Year General Health Guarantee, our kittens arrive fully vet-checked, with first shots, regular deworming, and expert socialization from day one. Our breeding care matches the love we pour into raising them.
How do we uphold this elite standard?
We breed and select only the HEALTHIEST Champion Breeders—quality over quantity, always!
No cat can ever call itself a Champion Breeder in this cattery without first passing these key health benchmarks:
Perfect DNA Profile: A flawless score (50/0-N/N) across all genetic mutations, ruling out hereditary risks.
Optimal Heart Health: Precise measurements of heart wall thickness and function, confirmed by full echocardiogram.
Sound Hips and Joints: Clearance on nine specific orthopedic checks, verified through comprehensive hip dysplasia x-rays.
Elite kittens can only be produced by Elite parents!
We’re ultra-selective, but even after 18 months of all these tests and close monitoring, two out of every three kittens we evaluate for breeding fail to make the cut to become a champion breeder. It costs a lot of time and money to source these superstars, but once a cat passes all of our health standards, they deserve the right to be called a, Champion Breeder.
As a Maine Coon breeder we’re not perfect—no breeder is—but we’re darn close. We coined the phrase, “It was our kitten before it became your cat.” Meaning, this is a true partnership, powered by our collective goal to provide the best quality of life for these amazing kittens. The benefit, every adoptive family experiences the full magic and potential of the Maine Coon breed.
Life here gets delightfully chaotic with these outgoing Maine Coons, but they’re endlessly entertaining and the ultimate roommates.
