6qt tub, one 4" clay or plastic planter saucer, newspaper, small water bowl, possibly some balled up newspaper or paper towels.

Stick this whole thing in a dark place, where it remains dark the majority of the time. No handling, change water every couple days.

If you can get a live small adult mouse, try that. Sometimes they just need a few live meals to get back on track, then you can get her back on f/t. Her eating is the main thing and that much weight loss isn't making me feel good.

None of my babies her size have ever refused food, even if they are in shed. Even my Enchi male, who is a shy boy, will still go after his mouse once I close his tub.

Try pre-scenting for a good half hour to an hour with the mouse in a cage next to her tub, in the dark. Use a flashlight, drop the mouse in her tub by the water bowl or on top of her hide, and close the lid. Back away slowly so you don't distub her with movement, and leave the room. Come back in 30 minutes to an hour and see if the mouse is gone. If it is, great! If not, just wait until next week.

Some of my more shy juvies I have in 6qt tubs that are tinted a dark grey. Sterilite sometimes makes different colored tubs throughout the seasons. If you want to try one of these, I can always send you one if you can't find one in your area. I have red ones too.

Also, what are her temps? Higher they are, the hungrier they are going to be I keep my babies at 82-84 room temp (ambient) and 94-95 hot spot.
