Murmurs seem to be the illness du jour of vets these days. I've heard a lot of people say their pet was recently diagnosed.

A second opinion and an ultrasound for peace of mind is a good idea.

Spunky supposedly has a grade 1 murmur. It doesn't affect his "spunkiness". He's always had mild asthma and allergies and I am suspicious of the murmur. It was the second vet that heard the murmur. Her bedside manner needs work. His primary and my favorite never heard the murmur. Of course, Spunky likes him so much, he couldn't hear much past his purring.

I supposedly have a heart murmur, too. I am wondering as we age if we all aren't susceptible to a little bit of slosh in our valves.

I wish your friend and her cat good luck with this.
