I always wanted to get a pet iguana. They are herbivorous lizards from Central America.
Wow, that's an exotic pet! How big do iguanas get?
They can range in length depending on species. The biggest ones can be almost six feet!
Whoa! I can't imagine! And they are herbivorous, so no meat? I wonder what their favorite thing to eat is. 
That is correct they are herbivorous lizards. They like all kinds of greens such as kale and lettuce.
Oh I seem to remember a kid I knew years ago had an iguana and they fed him lettuce. I wonder if they are very interactive with humans when they are kept as pets. 
The green iguana is a popular pet and does interact with their owners. Especially when they know they are getting fed.
Ha, funny how the food brings them around. Do iguanas come in different colors? I think I have only seen green ones.
