Thanks for the responses, guys, I appreciate the input. I'll wait it out and feed him on day 14, then. There are just so many different things when researching snake stuff, it's overwhelming.
We've left him alone, only times I've handled him were during spot cleaning when he's tried to climb up my arm, just setting him to the side and continuing to do my thing.

Do you think a pinkie mouse would be a better meal, then? They can be quite a bit smaller than rat pinkies... though I'm not sure switching back to mice is a good idea since he's already on rats. ?
We do not have a scale anymore, lost it somehow when we moved over the summer. But I know I need to get another one soon.
