Hmm...strange indeed. Only thing that came to my mind is maybe she got a cut or scrape on her nose or mouth while swallowing the mousey and it's irritating so she's rubbing her nose on stuff. But even that probably doesn't make much sense since you said there are no visible cuts or scrapes. I dunno. Hope everything goes well.

Edit: I was just looking for some bp feeding videos(preparing for my first feed tonight, lol), and randomly stumbled across a forum with a person asking why their snake was rubbing their nose on the ground and stuff. Here's a quote from a reply:

Lets see, reasons snakes rub there face.... shedding, jaw over extended, assist food down, mites, etc. Never heard the mouth rot one though. Its common for replacing the jaw and shedding. Sometimes,he could be just scratching too

I hope your wittle bp was just re-aligning the jaw or had an itchy nose. The mites and mouth rot thing would just suck. :cry: I guess the jaw over-extended thing might make sense since you said you fed her the biggest mouse yet.
