Hi, One of my rats, Benji is almost 30 months old and has developed severe nasal congestion. He's always been a bit sneezy but never been much bothered by myco but it looks like it's finally caught up to him. He looks and sounds like he's really struggling to breathe. The vet said his lungs are fine and he's not gasping so he'll be okay but gasping sounds exactly like what he's doing and it's obvious to me he is suffering. His nose is almost totally blocked and he's not getting enough air through and I can feel his chest heaving with the effort. Ive seen him mouth-breathing a few times for short periods. He's on Baytril and doxycycline but it's difficult to get him to take it as he's hardly eating anything anymore. I've waited four days for him to improve but it's not happening and he's old. Does anyone have any advice? I have lots of experience with pneumonia and chest congestion but not nasal congestion as bad as this. How can I relieve his symptoms? I'm thinking of spraying some oxymetazoline at him which is really effective for blocked noses. I'm desperate, he's in such obvious distress and if it's time to let go I don't want him to suffer and linger.
