I hate chain pet stores that sell reptiles. MOST not ALL have no bussines doing so. MY local petsmat does only keep one ball per tank and anytime I'ne been in there it looked ok to me. PetCo is the WORST! I went there to get some feeders and they had 2 tanks with balls. 3 or 4 in a 20 long, all with stuck sheds and looking unhealthy. I walked around to the other side of the display case and theres anoth 20 long with 4 red tail boas in it. They looked better then the balls but I'm willing to bet that they were only in the store for a few days.
