From the past few days Dobby is acting kind of weird scratching one of the walls. I have read that they do this with the clear walls but this one is a wood wall.
I would place something smooth agains that part of the wood on the enclosure if that is a fav spot for him to rub/scratch against, you would not want him to injure his neck skin and create an open surface on the skin....
She started to scratch that area a few days ago and it doesn't represent any problems her scratching it cause the wood is sealed with a very thick coat of polyurethane sealer.
Just concern of why she is doing that!
