I have noticed a few times that my female will come up to the glass late at night and push against it and then start sliding upwards to the top of the vivarium so I can see her ventral scales. Is this snout rubbing? (the first part) - if so can I do anything to stop it? She doesnt have a sore mouth/nose or anything, but it looks like she is trying to go through the glass.
Sherman does this too. Usually when he's exploring and wants to come out and play. Realistically though it's probably checking the boundaries of its enclosure for possible escape routes, knowing what escape artists royals are.
