Hi everyone. Today I caught my little guy flipped on his back three times. In the past hour. Right now he's in a square bookcase I just set up yesterday (I've only had him for about a week) and I was wondering what the best way to climb-proof the corners is, as I keep catching him in the act. I had a flower pot embedded in the substrate in one of them, but he still manages to push it over/out of the way. If it's relevant, he's only about a little less than three inches long. I'd post pictures of the enclosure, but I seem to be having trouble uploading, haha. Thanks ahead of time!
