depends on the breed of the chameleon, the more popular and widely pet-isized(yeah i know it's not a word, but i'm special like that) type have roughly the same body mass as a parakeet.

iguana's are cool as hell i love 'em i've had 5 so far =/ the only downside is it's hard to keep them alive for longer then a year, and if you can grow one to the entire 5-6 feet they can get (sounds aot bigger then it really is, their tails are roughly 2/3 of their length) you're either damn good or damn lucky
