Mike, is your rat breeding anywhere near her enclosure? If yes, that may be an issue with her...If not, I have one in my collection that if I walk by, he may strike out due to the movement past his cage...If when you open her enclosure and give her a little tickle with the hook (to let her know youre there) and shes fine with you taking her out or picking her up; then I would suggest maybe blocking her view with paper or something so that she wont hit the glass if someone walks by...Sounds to me as if its just a strong feed response....nothing to worry about...


Good luck!
