I found a baby flying squirrel in my house that had been abandoned by its mother. Found it 2 weeks ago, unsure of exact age. I have been doing as much research as possible to make sure this baby survives and to my knowledge everything was going according to plan until recently I started noticing a clicking noise and after reading some of the posts in this forum I’m now terrified that he has aspiration pneumonia. He still has a big appetite though so I’m unsure. As far as lethargy is concerned, I feel he is always sleepy after he eats but always energetic when hungry. I just can’t tell if the clicking noise is from his breathing or if it’s from his mouth. It doesn’t seem to be constant which makes me think it’s just him smacking his lips. Please if someone could help me determine if he is in danger or not it would be a god send. I can provide videos if needed
