My ball python died suddenly. i recieved my firefly and fire about 6 weeks ago. i also have 22 other balls in my collection. They seem fine, ate every week live rat pups. Then on Dec. 8 i fed them both, the firefly regurgitated his food 2 days later. on dec. 16 they both refused food ok no big deal, but then i pick up the fly and he was doing a lot of twisting up, and he was very weak. Today Dec. 17 he died. please let me know any input Thank you.
