Thank you for the replies!

I hear you but I feed him in a separate bin because that was how I was taught in the vet's office. Sure they hardly bite but it's the problem with bedding that could be accidentally swallowed and risk of infection to his housing if say the mouse got fluids on his bedding without my knowledge along with him learning "Bin = Feeding time" I was worried he would be stressed at first and if he was I would have put him back in and just tried a different time slowly getting him used to it, but (assuming because he lived in a bin before) he just slithered around until I presented the mouse and he took it right away and after he swallowed him I waited a spell before carefully putting him back, no regurgitation signs or issues. He had water and a heat lamp while in the bin and went to his warm hide straight away after.

My only concern is that it seems he is in the process of shedding, his eyes started to turn milky and his skin fading, the works. But a few minutes ago I heard him wheeze. I've been keeping his temps and humidity to opt while he is in shedding stages like I was taught, but I also remembered they tend to wheeze or make popping sounds when they go through the process. I am still taking him to a vet to be safe and keeping him hydrated, but I know how bad RI can be even with vet help.
