Hi, it is normal in my experience for them to go a little bald and for their hair to get a little longer - I think this is due to hormones changing- like an old man would
His breathing looks normal.
Is he in his cage in the video? Or is that his cage behind him?
If he is out of his cage maybe you could time it so he goes back in his cage and can sleep in his house when he is tired, the plastic might be making him hot and this may make him uncomfortable
So glad he is feeling better
