Hey, so long time no post

Today I saw my female leopard gecko Rango licking her anal (not sure if this is the correct word) region after she defecated, I'm gonna assume it was to regain some of the nutrients that she may have lost in the excretment? I've seen the other female do this too. Has anyone else witnessed this. My one idea is that most leopard geckos are kept on tile or some other pointless substrate so I can safely guess that she is cleaning that region from any sand/dirt that may have stuck.
