Petco's are very hit and miss. The one I usually go to does a pretty good job with their reptiles. The enclosure are clean and temps and humidity are within parameters. Some of them are really horrible though. Their is a small pet store near me that is just terrible with their reptiles. Enclosures and water bowls are filthy. The people their have refused to take a snake out of a tank because they didnt like snakes. If they won't take them out then how are they cleaning and feeding and such. It's a shame when that happens. Unfortunately if you buy an animal to get it out of there it just gives them money to buy more.
