I fear he is a bit further along that what it seems. His mucous is foamy, and he does have a wheeze and is puffing out his throat every now and then. I assume that is related to the mucous in his throat. But he is still active, and plenty strong. Just more cooperative than usual, especially to having his head restrained. No signs of weakness so far.

I will make an appointment with his regular vet tomorrow. I'm assuming they will keep him on the meds he's on now. I read that if he did not respond that an xray of his lungs need to be done. I'm hoping it won't go that far and he'll respond to the meds.

Thank you very much for answering my questions.
