I use hemp substrate for mine and she loves burrowing through it. She's also got a plastic leafy thing she likes to hide behind, a branch and a rock to rest her head on
She's really easy but not eating at the moment - it's supposed to be hoggy brumation time.
As for the possibility of biting, keep a bottle of alcohol nearby (any excuse

) in the past I've keep some next to my monitor's viv, just in case - they don't like the taste of it.
