i have a ball python who's a few months old. today i fed her a hopper; she took it and killed it, but didnt eat it. i know balls are hesitant to take food, but i havent heard of them just killing and not eating. i fed her in a box seperate from her tank. it seemed that she couldnt position herself to swallow head first, and after a while i guess she gave up. i put the box (with my snake and mouse) back inside her tank and left it alone. it's been about 5 hours and she just retreated back to her hide box. any suggestions?
