Okay it's either the way you word things Mike or my warped sense of humor (or that it's 1 a.m. and I drank waaaaaaaay too much coffee) but I had to chuckle over the image of your snake and it's "stern look" at that mouse and then them both napping at opposite ends of the enclosure.
Makes one wonder if the snake was thinking "okay look you lil fuzzy bugger, I don't wanna eat you, you don't want me to eat you, so go crash over there till the Big Guy With The Forceps shows up again!"
Hope you get this sorted out though. It must be a daily worry with such a young one.
