Ok, today is feeding day for my ball python. Im was planning on feeding her two mice. So I put in the first mouse and she ate it no prob. But then I go and put in the second on after she had completely swallowed the first one and her jaw was back to normal. The second on starts crawling all over her and nipping at her head so I took ot out with tongs and it freaking attacked the tongs. Should I just take it back and get a new,less aggressive one?
