Do Cat heart murmurs get worse?
The murmur may first appear at 6-8 weeks of age, and a kitten with an innocent heart murmur will usually outgrow it by about 4-5 months of age. This type of murmur is benign (not harmful). Some normal adult cats may have an intermittent heart murmur that shows up when their heart rate is increased due to stress.
Can a heart murmur get worse over time?

The loudest murmurs, suggesting more turbulence of the blood flow, can be heard over a wider area of the heart. Importantly, the significance of heart murmur does not depend just on the loudness: some quiet murmurs can indicate very serious disease, while some louder murmurs may be relatively benign.
Can a softer heart murmur be detectable?
A softer murmur may only be detectable in one place. It’s important to know, however, that the grade of the heart murmur does not indicate the severity of the condition.
