Hi Steve! I don't want to worry you unnecessarily, but do have a vet check him out as soon as possible...a chest x-ray (or even better yet, an ultrasound) would be very helpful as well...I only say this because FeLV+ cats are prone to lymphoma...Our Chinney developed a tumor in his chest just after he turned a year old. I just noticed one day that he was breathing just a little bit deeper and more rapidly...his chest quickly filled with fluid (we had it drained once, which helped...but our vet wanted to have an ultrasound done on him through a specialist...unfortunately, it was the weekend and we had to wait until Monday to take him in...Chinney never made it to Monday, his chest quickly filled back up with fluid and we made the decision to let him go on Sunday night)...if I had known better, I would have told my vet to skip the ultrasound, that the mass was more than likely a tumor, and to start him on chemo ASAP...
I'm hoping beyond hope that Loki doesn't have cancer, but if his lungs start filling with fluid, there isn't much time...I would get him into the vet as soon as I could! Sending out positive vibes to you and Loki!! Jen
