Hypertrophic cardiomyopathy (HCM)
A thickened heart muscle disease reported in Bengals in breed-specific echocardiography research; a US veterinary school has run a dedicated Bengal HCM study programme. No breed-validated DNA marker exists for Bengal, unlike Maine Coon or Ragdoll, so echocardiography is the only way to screen for it.
What to ask for
No breed-validated DNA test exists — ask for a recent echocardiogram, read by a cardiologist, on both parents
