I am so glad you are in on this discussion! We rarely hear from the "other side" (er...the Dark Side

).
I agree that housing for pet shop livestock can't realistically be perfect. BUT, when potential buyers see an animal new to them, they can't help but want to mimic the caging they see on display out of sheer ignorance. I realize too that many customers never think the purchase through enough to ask questions about care. And, if an associate does not explain that the housing is only temporary and not ideal, the buyer has no clue they are heading into trouble. Like many on this forum, before deciding if I will become a regular customer, I test a pet shop's (yes, including PetSmart or PetCo) expertise by asking husbandry questions, including questions about the proper housing setup for a particular animal. I can't recall
a single time a store associate has said "our cages are displays only...your permanent setup should be...etc.". I recall seeing a screen cage in one or two stores, but they were completely inadequate for an adult cham such as a veiled. Tiny things about 24" on a side.
Are the species specific care sheets readily available with examples of what should be done instead? Even pictures posted at the displays would help. The mass-produced husbandry books most stores sell are outdated at best downright misleading at worst. Does anyone review these books to see if they should even be stocked?
It has been a while since I have looked at herp related products at either a PetCo or PetSmart so hopefully the supplies they normally carry has improved. I can remember not so long ago I was shopping for
correct UV lighting such as a ReptiSun 5.0 and none of these stores carried them. They all stocked the incandescent "full spectrum" basking bulbs but it is now well known that these bulbs do NOT produce the correct UVB needed. I can't count how many times new forum members were told this was the only lighting needed by pet store personnel. How many times have I seen the single water bowl, no foliage, and sand substrate in a pet store display of chameleons? Time and time again. No obvious other source of water...even a spray bottle standing at the cage side (and an explanation about misting by an employee) would be better.
If the corporate climate is changing and better attempts to carry the proper supplies and caging are being made I am glad to hear it. Guess the "trickle down" effect is still in infancy.
