It's almost been a year and Chelsea has come a long way! I'm glad I listen to everyone here on this website because if I listened to her doctors, who knows where she would have been right now. She has a heart murmur rated a 6, the worse. I didn't have the money to get the ultrasound-scans done and I was told that there wouldn't be anything I could give her anyway to correct the damaged heart. She's healthy, active, and doing so good. She's finally mellowed out with my other cat and they play and get along much better. All I can do is give her my love and care for her the best I can. I keep her indoors and feed her good food.
Many cats have murmurs...I wish you well with Casper. I'm sure he'll be fine!
