Typical behaviour. After It eats it'll chill in the hot hide digesting for a while. Don't forget, they're cold blooded. Without heat, digestion doesn't happen.

About the biting, if you can remove the tub or w/e she is in from the rack do so. If it's in an aquarium remove the hide from the back so she can't tag you. Once you get the hide up gve her a sec to understand that it's not feeding time and shell start to roam or ball up. Wash your hands before you handle your snake. Then grab her from the back.

If she starts tensing up in your hands a lite tap on the nose will tell her "no". But then again, it can make them head shy too... If she's tense, get ready for a bite. If sha roaming you're generally ok. The gloves would be good to get her use to people.

Hope this helps, Jeremy.
