I have a diamond python that does not seem to be moving the lower half of its body?? No incident happened that could explain why, after a bowel movement its lower body has gone rigid, kinked and tense and isnt moving. I am so worried that it has somehow broken its tail or back as i am new to owning a snake and was hoping anyone might have some advice please? Temperament has been fine and it seems to start moving then stops when the lower half of its body doesn't respond....??
