One of our local reptile stores had a terrible problem with thieves up until a couple of years ago. They had no room for displays and so their baby snakes were stacked everywhere, the amphibians were in a tank right by the front door, beardies in the front window, etc. etc. It was a very old building and the owner didn't have enough money to remodel until they had a fire (don't think they lost too many animals) and the insurance finally came through and he was able to afford enclosures with locks and an improved security system. Because yes, people are [losers] and will steal ANYTHING.
