my ball python is rubbing its nose against his tub

is this normal? I have never seen this with my other snake. MY ball python is rubbing his nose against the walls and on the ground. I know he doesn't have an RI because I can't hear any wheezing, his mouth is closed when breathing, he has no bubbles coming out of the mouth, and he eats great. Also no mites.

is he shedding?

its hard to tell for an albino but i dont think he his shedding

huh, mine does this sometimes, he'll rub his nose around, and then he'll kinda dig a little hole in the dirt so he climb under his hide instead of using the door, or he'll plant his nose down, and lift himself up like hes trying to force his way underground, its kinda ammusing to watch honestly, this is what he did, hes on coco
