Yeah, it is on the inside. However I did round them up pretty good not to leave any pointy edges that would be easily peeled off. Still, will be part of my regular inspection to make sure they are not coming off and replace if necessary.
Also this is a temporary set up just until the little fella gets bigger. I do plan on getting him a decent terrarium but didn't want to spend twice on one as getting a big one right away could have also contributed to stress and no eating as a baby.
