My cat died a horrible death. I thought he was just stressed like he always is after a vet visit, but by the time I called the vet to say that this incident was different, it was too late. He had a heart condition and that was what was going on, he was going into heart failure. I blame myself for not calling the vet sooner so that I could have at least taken him and he could have been spared the agony (he was dying, I know he couldn't be saved). I also blame the vet because when I did call her and expain his breathing sounded congested she didn't realize wht was going on with him.
