I own 6 other pythons and this is my first headache, I got a 4 month old about 2 weeks ago, and it was hissy at first, but now it lets me hold him, but he wont eat, I offered adult mice and today I offered a live pinky, and it hisses at me trying to strike me not even caring about the pinky. Seems like I have no choice but to just let it get comfortable and wait, any advice?
