The Maine Coon is a naturally developed breed that evolved over the last 200 years in the cold, rugged climate of the northeastern United States. In general, Maine Coons are a healthy and hardy breed, with no more health concerns than most other cats.
Responsible breeders, however, take additional steps to protect the health and future of the breed. Through genetic testing, health screenings, and careful selection of breeding cats with low inbreeding coefficients, we work to reduce the risk of inherited diseases and help ensure healthy generations of Maine Coons for years to come.
While no breeder can guarantee a cat’s lifelong health, comprehensive health testing significantly improves the chances of producing healthy kittens and maintaining strong bloodlines.
Our Health Testing Program
All of our breeding cats undergo extensive health screening before being included in our breeding program. This includes:
* DNA testing for known genetic conditions
* Heart screening (echocardiogram) for Hypertrophic Cardiomyopathy (HCM)
* Hip evaluations for Hip Dysplasia (HD)
* Testing for parasites
* Screening for FeLV (Feline Leukemia Virus) and FIV (Feline Immunodeficiency Virus)
Only cats that pass all required health screenings are used in our breeding program. Cats that do not meet our standards are spayed or neutered and placed in loving pet homes with full disclosure of their health findings.
Genetic Conditions We Test For
HCM – Hypertrophic Cardiomyopathy
HCM is a heart disease that can affect all cats, including mixed-breed house cats. In Maine Coons, one known genetic mutation associated with HCM is the A31P mutation in the MyBPC3 gene.
Cats inheriting two copies of the mutation are at high risk of developing the disease, while those with one copy may have a slightly increased risk but often remain healthy for many years. Because not all cases are caused by this mutation, regular heart ultrasounds are strongly recommended throughout a breeding cat’s life.
SMA – Spinal Muscular Atrophy
SMA is a rare inherited neurological disorder affecting muscle function. Although uncommon in Maine Coons, it can be severe in affected cats. Only cats inheriting two copies of the mutation will develop the disease, making DNA testing an effective way to prevent affected kittens.
PK Deficiency – Pyruvate Kinase Deficiency
Pyruvate Kinase Deficiency is an inherited blood disorder found in Maine Coons and several other breeds. Carriers remain healthy, while cats inheriting two copies of the mutation may develop disease. Responsible breeding practices and DNA testing help prevent affected kittens.
Blood Type Testing
Most Maine Coons have blood type A, but blood type B also occurs. While blood type B is not a disease, incompatible blood type pairings can cause serious complications in newborn kittens. DNA blood typing allows breeders to make safe breeding decisions and avoid these risks.
PKD – Polycystic Kidney Disease
PKD is an inherited condition characterized by fluid-filled cysts that develop in the kidneys. Over time, these cysts can impair kidney function and eventually lead to kidney failure. Because PKD is inherited as a dominant trait, affected cats should not be used for breeding.
HD – Hip Dysplasia
Hip Dysplasia is a hereditary condition affecting the hip joints and can occur in all large cat and dog breeds. Mild cases may cause little discomfort, while severe cases can result in chronic pain, mobility issues, and significantly reduced quality of life.
Research shows that kittens born from parents with normal hip evaluations have a substantially lower risk of developing severe Hip Dysplasia. For this reason, all breeding cats should undergo hip screening before entering a breeding program.
Health testing is one of the most important investments a breeder can make. By combining DNA testing, health screenings, careful pedigree analysis, and responsible breeding practices, we strive to produce healthy, well-adjusted Maine Coons that will be cherished members of their families for many years.
