A New, Easy-to-Learn, Stress-Free Method to Stop Purring During Cardiac Auscultation in Cats

Purring is one of the most endearing feline behaviors, but when it comes to cardiac exams, it can be a real challenge. A loud purr can easily drown out heart sounds and murmurs, making it nearly impossible for veterinarians to perform a proper auscultation.

A new study has tested a simple, stress-free technique that helps silence purring long enough to allow for accurate cardiac assessment.

How the method works
The technique is straightforward: gently grasp the cat’s larynx from the ventral side with one hand while holding the stethoscope in the other. This gentle maneuver interrupts the vibration that produces the purr, giving the clinician a quiet window for auscultation without causing distress to the patient.

What the research found
Researchers evaluated the method in 582 cats across a veterinary teaching hospital and a cat-friendly private practice. Of those cats, 51 (8.8%) were purring during their physical exam. The new method successfully stopped purring in 89% of cases.

Interestingly, the technique proved equally effective whether performed by a veterinary student or a seasoned cardiologist, suggesting it’s easy to learn and apply. The frequency of purring was also consistent between the teaching hospital and the private practice. However, older and sick cats were more likely to purr than younger, healthy cats.

Why it matters
Accurate cardiac auscultation is essential for detecting murmurs, arrhythmias, and other heart conditions. Having a reliable, cat-friendly way to quiet purring makes exams easier, reduces the need for repeated handling, and improves diagnostic accuracy.

This approach builds on the growing emphasis on stress-free, feline-friendly handling in veterinary practice. Not only does it help veterinarians perform better exams, but it also supports a more positive experience for cats and their owners.

Takeaway
Purring may be a sign of comfort, but in the exam room it can complicate heart health evaluations. This new, easy-to-master technique offers veterinarians a practical tool to ensure accurate cardiac assessment—while keeping feline patients calm and stress-free.
