I do not wish to be the bearer of bad news, but part of the reason that his lungs are clear is because of the lasix. I have trouble conveying this to the owners of my small animal patients who are in congestive heart failure. I am keeping my fingers crossed for you that this was just a very severe case of pneumonia but if you cut back on his diuretic please do so under the guidance of your vet so you can make sure he doesn't develop pulmonary edema again. If it is heart failure, the more times we allow the edema to develop, the harder it is to get things managed again.
I honestly am not trying to be a pill and I REALLY hope things go well with him, but with how rapid his response was to the meds I fear the worst. Pneumonia does not generally respond to antibiotics so quickly so I am worried it was the edema responding to the lasix. I will keep my fingers crossed that he does well as you back off on the diuretics.
