Around here (NorCal), Petsmart is worse than Petco when I've always thought the opposite. The ball pythons and reptiles at petsmart always look so.. not well. Today I went to Petco to get some quick fuzzy mice (as I don't need too many so can't really order a box of them online) and noticed they made changes to their reptile department, which pleased me. The leopard geckos are on turf (solid piece) instead of whatever they had before which is usually repti-bark. The boa constrictors were on eco earth to help with their humidity (it was wround 50% the highest I've ever seen in one of those stores). The boas looked okay to me, so I was genuinely impressed with their improvements, even if they were small.

If someone gets a job and knows their stuff, they definitely make improvements - as far as I've seen.
