Niima your right but you wouldn't go to a home improvement store and expect them to hold your hand or a auto parts store or any retail environment you follow instructions yourself or google you go looking for the education just because we work at Petsmart doesn't mean we are all herpetologist and some people there may know a lot about birds but little about hamsters but they still have to sell them and try and answer questions I research everything before I buy so I know what I need before I go into the store no matter what it is even if I do this more for my herps than my car
