Franklin went to the kitty cardiologist today for a check up and we received good news! There was no change in the amount or location of his heart enlargement, the obstruction is gone, his heart rate was normal, no "fluttering"' and his murmur is softer! Which means the meds are working. Cardiologist doesn't want to see him for a year.
He still has a serious condition, one that will most likely shorten is his life but at least for now he doing great!
