I'll add it with everyone else.
DONT BUY SICK AND POORLY KEPT ANIMALS FROM BAD PET STORES. It's not a rescue!! It's giving them money to buy more animals!
I know for a fact from working in a Fortune 500 corporation in operations; they look at the numbers of what's been the hottest selling animal, and will "bulk up" more in the future. They are really about money!
Your better off complaining to them, then to the better business bureau. Get them in trouble instead of taking it into your own hands.
