Thanks both LoudLou and Tatsxxx11

I picked Kedi up at the vet earlier tonight. They gave him a shot of cordizone and a duiretic (spelling?) to see if that helps. If so, then we will get a prescription for them.
In the meantime, something is going to be set up with a specialist. I guess he is difficult to get in to see, so it may end up being late this week or early next week.
We are suposed to keep Kedi from getting stressed or playing until then- it's kind of difficult because we also have a 1 yr. old kitten and a dog.

Tatsxxx.....yes, one of the things that was brought up was Cardiomyopathy like you mentioned. The vet did blood work and took x-rays. He was on oxygen for a few hours. His heart is quite enlarged, and his lungs have fluid that has also caused bronchitis.
I guess we won't know anything for sure until the specialist runs some tests.
Oh. And by-the-way: your Mr. Big looks ALOT like my Kedi. Long hair, creamy-white, with some orange markings, and blue eyes.

One good thing is that he seems to feel fine when he is not wheezing, etc. I am just glad that he is not suffering right now.
