I used to work in a Petsmart and I tried my best to keep the reptiles (especially the snakes) healthy. Unfortunately, Petsmart has a few policies in place that make it hard for them to be cared for. They use the dial type temp gauges and those are very unreliable. We did our best with what we had though. There were several times where I broke company policy to save a snake. Sometimes (not always, but sometimes) the employees are very knowledgeable but the company policies won't let them care for the animals properly.
