Denise, I just wanted to offer you a little encouragement. We have a 16-year-old fur baby that was diagnosed with congestive heart failure two or three years ago. He takes Lasix (and a host of other medications) and has trouble dealing with the heat and humidity, but has managed to pull through the last two (hot, humid southern) summers by staying inside most of the time. His hips are now giving out and I'll be very surprised if he makes it to and through summer, but I refuse to think about that now. In any event, I wanted to let you know my thoughts are with you and your family.
