Also, do you know anyone who's ever had a cham get seriously hurt from substrate? From what I've seen it's a thing that most people avoid, even though there may not be much proof against it. I mean chameleons do live in the wild and they can't always choose where they eat their food. I can see large pieces of bark getting stuck in their throat, but a more fine powderlike digestible coconut substrate should be fine. Then again, I haven't had experience but I've seen pet shop owners keep chameleons with substrate and they say it's fine.
also, just because a pet shop owner does it, doesnt mean its correct.
we have had many new owners say the pet shop owner said:
you only need this red light bulb.
give calcium with d3 everyday.
canned, dead bugs are fine to feed them.
keep your baby cham in a fish tank until its older.
they dont take up alot of space.
keep a bulb on at night so they dont get cold.
their tails grow back if they fall off (Yes i saw someone who said a shop said that)
they need a waterfall or a bowl of water to drink at all times.
they are hard to care for and die easily (only when taken care of improperly)
pet shops forget to warn owners that girls lay eggs even when not bred.
These are just some of the lies and stupid responses pet shops give on how to care for cham correctly.
Do you really want to trust a pet shop person who either A- has no training or knowledge about chams or B-is just trying to make a sale of a highly priced item.
