[4] The current oldest verified cat alive is Flossie, who was born in 1995 in England, United Kingdom. [10]
Not all cats that test positive will have clinical signs of the disease, and some Maine Coon cats with clinical evidence of hypertrophic cardiomyopathy test negative for this mutation, strongly suggesting that a second mutation exists in the breed. The HCM prevalence was found to be 10.1% (95% CI 5.8 -14.3%) in this study. [39]

A UK study looking at veterinary records found a life expectancy of 9.58 years for the British Shorthair and British Longhair compared to 11.74 years overall. [22] Swedish insurance data puts the median lifespan of the breed at >12.5 years. Eighty-two percent of British Shorthairs lived to 10 years or more, and 54% lived to 12.5 years or more. [23]
