It sounds like her environment is stable, and she’s in capable hands, but I agree that a 10-14 day feeding schedule would be better. My adult colubrids eat every 12-14 days. I can see why she’d take a break from eating weekly. A month off food is no big deal for a healthy snake. Adult mice are fine but if she’ll take them she could also eat small chicks, rats, African soft furs, or quail. Nothing wrong with a diverse diet. Most of my snakes eat 2-3 different types of prey.
