Wait, what?

It's not good to have more then 1 BP in a cage?

Why in petstores do they have one cage full of them?

My uncle who has had many exotic animals, and lots of reptiles for many years ( alligators, turtles, snakes, lizards ) told me this wasn't a problem at all, just make sure i have my current one checked before i do put them in that way the don't contract anything from each other?

I am fairly new though i guess, but i'm honestly shocked that this isn't good.
