kitten has heart murmur

post #1 of 6
Thread Starter 
hey everyone,
been to the vets today and found out that my 13 weeks old kitten has a grade 3 heart murmur. the vet said that is was quite common, but just wondering if anyone has a cat with a heart murmur and if they do anything special for it or anything.

This thread is just above yours and talks about this problem.

Here are two of my threads about my kitty with a high grade heart murmur. There's tons of valuable info reguarding anesthisia in the second one

I haven't had any experience with this. Hope your cat will be okay.

I didn't understand with this. Anybody else could explain?

A heart murmur itself in a kitten isn't diagnostic of anything - you would need more testing to know for sure what it could be an innocent murmur (that means there is a murmur but it has no effect on the cat) or it could be heart disease (ex: cardiomyopathy). A lot of times, kittens will be born with murmurs and they will disappear by about 6-8 months. Some cats live with murmurs their whole lives and have no problems. (sometimes, the murmur is just a fluke - and you won't hear it anymore)

To test for heart disease, you'd need a chest x-ray to see if the heart is enlarged (which would indicate congestive heart failure), and also a heart ultrasound (at a kitty cardiologist) to see how the heart is functioning (sizes of ventricles and stuff). If there's heart disease, there are some treatments (which I am not familiar with enough to detail). If there is not, there is nothing you have to do.

My kitten has a grade 1 murmur and I am choosing to just monitor it for change and to see if it goes away by 8 months. I am also monitoring her for symptoms - looking for her having trouble breathing, changes in eating habits, less playing/other reductions in activity level, etc. So far she is one of the most active kittens I've ever had and eats like a horse - she seems really healthy.

The grade of the murmur doesn't really indicate the severity. Any grade could potentially be heart disease. However, it is less common that a high grade murmur is innocent. (your kitty's murmur could have just been louder, though, because he/she was nervous)

I hope the murmur is just an innocent one!
