Please, Please don't buy a cham from Petsmart-it only encourages them to get more. The only way I would take one from them is if they would give it to me to save it. I repeatedly see dead chams in one around here-you would think they would learn.
The only reason why I'd be buying them is if I could tell it was Gravid. I wouldn't want the mom and babies to die . But, I won't buy a baby from them.
