pedigreed cats or in any cat with HCM is other than a
familial autosomal dominant form of inherited HCM.
What I am hoping might be investigated is the
possibility that catecholamine (sympathetic
activation) could be responsible for some myocyte
damage resulting in hypertrophy in some felines.

feral colony has and one would have to wonder not if
but how imbred a feral colony may be. Because of feral
TNR groups the kittens of these ferals are being homed
through no-kill shelters. The feral background of
these kittens is often not disclosed.
I realize my catecholamine cardiomyopathy hypothesus
is not what we currently know and accept as fact
regarding HCM in felines but if it weren't for a Maine
Coon breeder approaching a vet cardiologist and
donating a line of Maine Coon cats would we know as
much as we do now?
BTW I also found studies showing that dolphins briefly
ensnared in tuna nets suffer cardiac damage from
catecholamine. In humans this type of damage in seen
in torture victims.
For those of you dealing with CHF, the use of
beta-blockade to block catecholamine in addition to
angiotensin-converting enzyme inhibitors is now the
standard in human CHF.
