Mary,

I wish I had more information for you but, I have had friends that had cats with heart murmurs and they needed no treatment and lived normal lives. These kitties where thought to have had these heart defects from birth. I would keep up the hope and I would not worry yourself until you know what's going on. My thoughts and prayers are going to you, Specs, and Puddy. Make sure you take care of yourself and not let yourself stress out too much, this can effect your own health. Just being there for you babies lets them know that they are loved and cared for. Big PT hugs to your babies from me, and my whole kitty gang. Please keep us updated!
