I got my 2 ball pythons from petco. The adult i got came from there someone droped him off and new nothing about him nor has anyone handled him until i came in. I adopted him and yet to have any problems out of him (which from my understanding he wasnt there long) And that very day they had baby bp's on sale for 15 bucks. Well i picked up one because i just moved my baby rtb into a bigger enclosure. I have had problems with feeding and with mites. But the baby bp has picked up on her feeding would i regret it no. shes still under isolation but no more mites and shes picking up on her eating been eating 4 weeks straight now. the petco around here seem to try and make a effort to keep up there animals but i know its rare you see it
