🫶 Murr-Murr and HCM (Hypertrophic Cardiomyopathy)

All of my breeding cats are genetically tested clear for HCM (Hypertrophic Cardiomyopathy).This means your kitten does not carry the HCM mutation and cannot have a genetic heart condition related to it.

However, it’s quite common for veterinarians during a routine check-up to say:

“I hear a heart murmur… let’s do an ultrasound, just in case.”

This happens often — many owners immediately panic, spend hundreds of dollars on testing, and later discover that their cat’s heart is perfectly normal.

A mild “murmur” can appear temporarily when a cat is stressed, frightened, or breathing rapidly during the visit.Even a healthy heart can sound irregular under stress — and that’s completely normal.

And yes, there is also a human factor: some clinics depend on additional, often expensive, procedures as part of their income.That’s why it’s so important for owners to stay calm, informed, and avoid making emotional decisions under pressure.
