So I checked on Sebastian and found him using his hind legs again. Thank God! I feel so much better now, knowing he'll be okay. I looked up information on him and found out that sometimes larger crickets cause digestive problems in baby beardies. It can paralyze their hind legs while the beardie painfully digests his food. I felt awful! I'm going to be on full surveillance now. No more big crickets for my baby!
Anyways, this was just a quick update just in case you were wondering.
Check back for more insights from Sebastian! :)
