gecko's can be mean. i forgot what kinda i had (it was a larger species i think it was like a takeyeko gecko or something, i know it' sstarted with a t, and kinda sounded asian) i only tried to hold it once, it bit the fuck outta me and made me bleed pretty bad (dont' understimate them, some have a mouth full of razor sharp teeth and don't like to be messed with) chameleons don't really do much, and if you want my advice i'd avoid reptiles all together (they all tend to get certain disease and die, and there's not really much you can do about it or prevent it, something that just happens, espeicially in iguana's) i have alot of experience with reptiles so i know a bit about them, i've had numerous anoles, few geckos, 2 horned lizzards, 3 snakes, 5 iguanas..only the snakes didn't die from this mysterious disease. i've had hamsters, rats, feeder mice, birds, fish.....best pet i would advise would be sugar gliders (atleast if you plan on holding th is pet) hamsters stink (you can clean that cage and within 3 days it smells like piss again >.<) and they chew like fuckin crazy and it will drive you nuts.
