Yep is it, we only keep one snake per tank if we can, only when they are baby cornsnakes, then we keep 2 to a tank. All reptile tanks are completely cleaned every thursday per the PetSmart P&P's and most employees use common sense and put a hide in the enclosure. Every snake tank and reptile tank we have has 1 or 2 hides, plants, a water bowl and either aspen, repti bark, or calcium sand depending on the animals needs.
Fortunately for people who live near my PetsMart, we actually have a pretty knowledgeable staff in Pet Care. The employees that even i don't trust usually open in the mornings. Also i am the snake guy at my store and anyone with ball pythons questions comes to me first, then again i just learned it all from here anyway, so at least its correct information. Plus i've made enough mistakes to know what works and what doesn't.
Oh yeah and i have NEVER EVER sold ANYONE dial thermometers and hygrometers. I always tell them to buy digital and go to walmart or home depot to buy them.
