This pet store is so sad...you are right most of these animals are in the wild, and should be! Glad you decided to pass on buying anything, I don't think many of them would survive too long in a cage, yikes. We have had pet stores hit by hurricanes in our area, now many of the animals released have become invasive and are consuming native wildlife. It's crazy!
I rarely buy anything from pet shops. It just encourages them. Sadly it's really common in Asia for random people to buy pets. It's hard not to think of the ethical issues when seeing it.
There are so many things wrong with keeping exotic animals and non-native species.
