I have a year old girl that did this last week with her live rat. She actually bit it on the back leg and got herself wrapped around it so the head was moving around. I sat there and held the tongs in it's mouth so it didn't bite her, but the worst part was she wasn't suffocating the rat AT ALL. It just screamed non stop. After like 10 minutes it slowed down and she started to unwind slowly, but once it moved again she started squeezing again but this time a different part and the rat stopped making noise shortly after. They usually figure it out where ever they latch onto.
