How would you feel about a caged bird in a retail store you were shopping in?

Just to comment: not all reptiles require being fed living beings.

The ones that come to mind are iguanids and uromastyxes.
I’ve had the former. They get rather large, require an extensive set-up, but have personality pouring out of all of their orifices. There are also -a lot- of them (green iguanas in particular) up for adoption.

Uros stay small, require higher temperatures, and are a bit less aggressive.
There are also canned foods for lizards which are partially herbivorous, such as bearded dragons. (Canned crickets, freeze-dried worms, etc.)

Gosh. Too bad nobody else thought to mention this. Perhaps a couple of days ago. In post 15 of this very thread.
