My six week old squirrel had a slight faint clicking noise this morning so I took him to the vet and he got an antibiotic shot and put on baytril , he was eating fine and still active but this evening he seems bloated and doesn't want to eat very much so I gave him some infant gas drops , is their anything More I can do ? And how extremely concerned should I be ? I feel like I caught the very beginning onset of pneumonia .
