glad to hear she is being spoilt!
hopefully the heart murmer is a slight one, our vet does check them before neutering so I am assuming it can't be too noticable (although i know its easy to be anxious especially when you lost Barney too soon).
its really great to hear how Bella has helped to heal the hurt with your daughter, you are both a good advert for finding room for a cat in your life
attached is a picture of bella when she was here and another of her two kittens that i think were both rehomed already when you met Bella. One of our volunteers is a photographer and she couldn't resist taking a photo of Bella and her little ones.
