I have a veiled. SOME Veiled chameleons consume veggies/plants. So you have to provide non toxic plants and greens. If you choose these you need to atleast have a lid somewhere high in the cage with cut up greens like collard, mustard, and kale. My veiled loves his greens. He eats them all.
My veiled chameleon is a male and I suggest you get a male if you don't want to deal with the eggs and possible death of egg binding.

I'll let the others give u advice, I am fairly new but not really. I have owned alot of reptiles and speacilize in all my animals

I have only had this one chameleon.
Once you choose something I would highly recommened posting a new thread on asking how to care for your choice and what you need. Without knowing which type, I am not sure many of these people can tell you what you need without the right breed of chameleon atm. And if you think you know everything I would still post new thread on your final choice.

Once you actually buy the chameleon and stuff. You should repost and see if your doing something wrong.(with pictures! if possible) Also fill out the info sheet on your chameleon once you bought one. At bottom of this post.
Also you should go to your "about me" section on your profile and put in your location. That will really help everyone tell you more about your chameleon. (you can see my location in the upper right corner of this post I made)
