Reddit reviews Iguanas For Dummies (For Dummies (Computer/Tech))

You don't want to wake them up when they are sleeping to handle them... Especially not an iguana. Iguanas do best with routine. Not all iguanas become tame. Iguanas are incredibly smart lizards and if you treat them with respect, understanding that they are smart and you are building a bond with the creature...you'll have a much easier time. It takes a while, and it's not going to be overnight, but with patience it'll mellow out.

I highly, highly recommend this book - we don't carry it, but I read it when I first started working with reptiles beyond my personal collection, and it was the most helpful book about iguana care I've ever read. Iguanas for Dummies

Good luck!
