Ok so we got a Stimson python (6 yrs old) roughly 6 months ago. She has always been handled and fed every 2 weeks. She had a rough shed a couple of weeks ago and since that she ate as normal, but she is striking at the glass and bit/attacked my 10 yr old daughter when she was filling up her water and spraying her humidity box. She has always been calm and placid and all of a sudden changed. Can anyone help as to why this could of happened?
