What do I do?

He does that noise quite often though, and he keeps half of his mouth open quite often as well. Does that happen with your retics as well?

The behavior comes and goes, and yes, they will occasionally lay mouth-open for a while. I usually take advantage and have a good look inside for mucous/bubbles just to reassure myself that there is nothing going on.

Now, what I won't do is tell you to take your snake to the vet, but I would not be surprised if you get various tests done for RI, and the vet finds nothing is wrong, other than your retic is being a typical male retic.
