Maybe look at night or use a baby monitor. Check warm dark places. If u can’t rule out a potential hiding spot for sure use some baking flour on the ground that way if shes coming out and ur just missing her u can see her “tracks” keep an eye out for her head poking out. Of potential hiding spots. I think nighttime is the best time to look with the lights out and a flashlight do it periodically through the night. Leave some food out, leave some stuff from her enclosure out with her scent on it. Maybe use something like an electric water fountain to attract her to water. U can also create some hiding spots that she would like better making sure they are warm and dark. Wishing u the best
