lizards are great pets depending on what type you get. I have a bearded dragon and hes great. Bearded dragons are really friendly and don't bite or get vicious, but after handling them you have to wash your hand. But a lizard is a good pet. Also they eat crickets but as they get older mainly veg and fruit. Bearded dragons live to about 8-10 years. Geckos are also good pets.

You should buy a small green iguana. They live more that 10 years, eat fruit and vegetables, are quiet, behave well, safe, you can hold it, grow to be about a meter and a half (including the tail). But if you get an iguana get a small one that way you can see it grow and make it used to getting touched. The problem with all lizards is that they need to be in a warm environment.

well it depends the lizard. i have a leopard gecko and hes harmless, they live up to 14 years and eat crickets. so if the teacher isnt afraid to handle crickets, its a great pet

depends on what kind..if your thinking a larger one like an iguana, no. smaller one like a gecko, yes. they are pretty cool to watch, easy to feed.
