The rat is smaller than his fattest part, but watching him try and get it in his mouth just seems like it is too big. I just want to make sure I'm not harming him by going from the adult mouse to small rat. Thanks as always.
If the rat is definitely smaller than the widest part of your snake it will fit. It's one of the most amazing things about snakes in general. With nothing but a mouth backed by a tube of muscles they can swallow things much larger than their head and neck in one piece.

If you aren't sure in the future, you can always weigh the food a few times to help you get used to what he can eat. 10% to 15% is a basic guideline. You do that a few times knowing it'll work, it'll help you start being able to eyeball things more confidently.
