hmm, well how long have you had him/her?
it may have already molted but is so small you didnt find it.
I've had the little sling for about a month I think, and I SWEAR it looks bigger, but haven't seen a molt. I figured it was possible it got buried, with him pushing all the dirt around.
Cause when push comes to shove you taste what you're made of
You might bend, till you break cause its all you can take
On your knees you look up decide you've had enough
You get mad you get strong wipe your hands shake it off
Then you Stand
