Most petsmarts in my area are terrible about their reptile husbandry. My wife and I have reported lethargic and half dead reptiles to management numerous times. They always come back with a "oh they just got that way today" or some BS line. I am not saying they are all bad by any means. I have seen more bad than good tho.
Their stick on hygrometers and thermometers are a joke. The animals are deliberately under fed so they "don't get too big" while at the store. As well as a few other things. I am not condemning them all, but there is a lot of ignorance in petco and petsmart when it comes to reptiles.
