      Hi

      HCM is more common for several reasons. In most cats HCM doesn't show up
      until after four years of age and by then they will have reproduced and
      passed it to kittens in pedigree cats. Screening by ultrasound is a fairly new
      development. A male champion cat with HCM which showed at age 11/12 could
      have had hundreds of kittens, all who could have been bred on. And the
      limited gene pool and matings of relatives will make this worse.

      I have 18 cats, 17 are pedigrees and 6 have serious heart disease and 4
      have minor disorders of the heart they were born with. All except three are
      symptomless but were diagnosed on echo. My breeding girl is a totally
      different line and HCM screened as negative for her last two echos.

      The other reason is cats are living longer due to better diets and vet
      care. So more cats who are elderly are surviving to develop HCM. And in the
      past without the internet people weren't in contact so much so cases tended to
      be isolated. The detection of HCM is impossible without ultrasound. Many
      HCM cats would have been treated for asthma or infection in the past.
