If she's active, it's likely she's stressed out. From the picture you posted in your other thread, her enclosure looks big and her hides are much too big.

Try a 6qt tub, with one 4" plastic planter saucer(hole cut in the side and turned upside down), and a water bowl. You can get the 6qt shoebox tub and the planter saucer at WalMart.

Once you move her, and she's settled in, her acting hungry will consist of her sitting in her hides with her head out("lurking"). Then you can pre-scent the room, turn off the lights and drop a live small adult mouse in her enclosure. She'd do fine on either a large hopper or a small adult mouse.
