I have had personal experience with a Petland in the past, it is thankfully shutdown now. I took in 14 syrian hamsters and a couple dwarf hamsters over a period of about a month straight from the store. The animals were overcrowded and fighting badly. They had bad wounds and two were missing an eye. The open cages allowed people to constantly bother the nocturnal animals and the one dwarf was psychotic. One employee admitted that they don't seperate males and females but it didn't matter cause they could use the pinkies for snake feed. That means the snakes you would buy would be conditioned for hamsters and if you buy a female hamster it would be pregnant but they didn't seem to understand the problems their actions could cause. The employees weren't trained at all, they barely even seemed to know the basics of the animals they cared for. At least they were willing to give the injured unsellable adults to me but I think its because they were taking up room in the back and they didn't have any snakes large enough at the time. When I would walk in and the employees were asking me questions that is a really bad sign.
