Hey! Today my tarantula has started digging themselves a spot in the enclosure to hide for the first time. I’m not worried about this but was thinking about putting a little tunnel like thing for them to hide in. The reason for this is the spot they’re digging themself seems a bit cramped and uncomfortable (they’ve appeared to have some difficulty menuvering around it). Is this ok for its enclosure (temporarily or permanently) or should I get something from the pet store instead??
