My tabby kitten, 2 months old, got Upper Respiratory System (we went to the vet) and also has mites in his ears. He's receiving treatment, but I googled up and discovered that he could have pneumonia? His breath is cackling and is pretty rapid and I saw that it was a general symptom of pneumonia. The vet never mentioned anything about pneumonia though..so am I overthinking or should I ask my vet again? I have never raised a pet before so any help would be appreciated, please! Other symptoms include (my vet knows about these symptoms) sneezing, watery eyes, and discharge from the nose. My kitten eats and drinks a LOT and is pretty energetic in the sense that he loves playing with his toys. But his breath cackling is still worrying me..what should I do?
