I house my ball in a good sized 41 qt tub. At first he was using the hides I provided him (two identical black bowls with entrance holes cut into them) but now he wraps himself around the hides and just lays on the substrate. I just want to know if this is normal. I'm not too worried about it because he's not roaming the tub nervously, just not staying in the hides. The tub is in an isolated room with no outside intrusion except for when I check on him. Does the tub provide enough security for him that he doesn't feel the need to use the hides?
