Kedi update: We have a prescription of diuretics and an apt. with a cardio specialist on Monday the 18th. He seems to feel quite a bit better today
however, he is not the same kitty he was. I hope and pray that there is nothing seriously wrong, and that some good meds will help.
Today he even gave us his famous 'kitty kisses' (nuzzles your ears- he is obsessed with ears!)

It was weird, but both my dog and other cat (Wylie) did not want anything to do with him for the first day after he came home.
I know it made him sad that his best buddy did not like him for awhile. Wylie was even kind of scared, and would not eat- I think he thought it was another kitty and not his brother.
Everything is back to normal now though. They are back to being lover-boys again

Once again, thanks to all of you for your kind words & wishes.
And tatsxxx (Sandra, correct?) thank you soooo much for the info you have passed on to me. It has made me breathe a little easier to hear that there is a good chance he will live and feel well for some time to come.
