Thanks for sharing this. Leroy had congestive heart failure. I didn't even know there was a problem. I took him in for a check up because he seemed to be loosing weight. He had lost 3 pounds but was a big cat - 15 pounds. They then heard the heart murmur. 3 weeks later, it had progressed so he could not breathe easy. Probably, fluid on his lungs. This confirms my and my vets opinion that he would only get worse. I'm even surer now that I did the right thing sending him on.
