Hey Trisha,
This heart disease issue is entirely on the shoulders of Big Pet Food. They realized, far too late, that their supposedly "100% complete" diets lacked vital heart nutrients. Those nutrients are present in balanced raw food like Steve's and others.
You're doing fine. And all murmurs are not due to this nutritional lack. There can be many reasons. Best is to hire a homeopathic vet to be your primary caregiver and steer clear of what passes for prevention from Dr. WhiteCoat these days.
