Only thing about carpet pythons is that they can be pretty nippy when younger. It's not a big deal but to someone new to snakes it can be a detergent getting struck at a lot.

Carpets are awesome, one of my favorite snakes, if you get a baby you WILL get bitten. But it's not bad, they calm down with age and our great handlers.
I love my dumerils boa, she was my next snake after my BP.
