Changed up the feeding regime starting this week. After much deliberation, it was decided to switch to feeding Alice in her habitat. With that change, I can feed her almost any time I need to and it eliminates any after feeding stress caused by moving her back into her habitat. I place the meal on a paper plate in her habitat to try to keep it off the substrate (aspen shavings). Once she has consumed the rodent and curled up in a hide to digest it, I remove the plate.
I do still worry about her ingesting some substrate however it seems the risk of impaction is very small. The pictures below are of Alice waiting to be returned to her habitat after I cleaned it today and of her “clean” habitat after she ate her dinner and tunnelled all over the place.
