As long as you picked your plant based off the ones recommended in the resources tabs, you should be fine. Unless it is a ficus, those plants can be toxic to the chameleon if consumed in large amounts.
Not really much point in my looking Clea, im not a botanist, Theres no way I can identify a plant by looking at it, unless its a shefflera or something, even then, some are ok, like arboricola, some are toxic like actinophylla, and they look identical.
Sorry.
our guy has been taking big bites out of the jade plant in his enclosure for a couple months, no side effects. It's funny because you can see the shape of his mouth on the eaten leaves - like a shark bite! Jade is a little like a smooth cactus so I'm sure he's enjoying the moisture content.
*sigh* Clea please get a PICTURE, youtube doesn't load on my computer all the time, and sometimes people don't like to look there, or it doesn't load for them, either.
