Pet's info: Cat | Mixed Breed | Male | neutered | 23 lbs
I have a male neutered cat and he has had issues w/weight and sneezing. He is in Lysine and just finished a round of Clavamox. He is also on prescription metabolic food to help his weight. I did another round of Clavamox becaus he sounded very congested as I explained to my vet. He even coughed up mucous. There is no nasal discharge with his sneezing. One week post Clavamox he is sneezing again and he once again looks very bloated. I’m wondering if some of his weight is fluid?

Hi and welcome to Petco Pet Education Center, formerly Petcoach! I am sorry that Miso is not feeling well. From the medications that Miso has been put on it sounds like your veterinarian may suspect Miso may have a virus causing the upper airway congestion, we sometimes use Lysine to help with viral upper airway congestion. The Herpes virus (along with some other viruses) causes chronic upper airway congestion. This can cause watery eyes (not always), sneezing and nasal discharge (not always)-recurs with stress. It can have a secondary bacterial component to it that responds to an antibiotic like Clavamox. Or this can be just a bacterial upper respiratory infection that is not responding well to the antibiotic of choice. Clavamox is typically an antibiotic that does well with upper respiratory infections. My biggest concern with your note is the looking bloated. I would have Miso evaluated by your veterinarian for looking bloated and discuss an alternate antibiotic, an antihistamine or I will even sometimes use saline nasal drops with a humidifier to help with moisturizing the airways. I hope this helps and good luck with Miso!
