My wife and I gave our kids a pair of tiny bearded dragons for Christmas. They are now probably 10 times heavier than when we got them 6 months ago. My kids aren't that interested in the beardies any longer, but I am.
They love to eat meal worms. I don't let them eat too many, because they need to eat their vegetables.
I like the beardies because they don't bite, they enjoy being held, they are active in the day, and they don't poop on me. As far as reptiles go, Link and Rosa are great pets.
