Chameleons in general don't like to be touched, handled or even looked at. They want to be left alone all the time. If you buy a baby (never purchase a chameleon that is under 2 or 3 months old) then they will get accustom to you handling them when you clean out the cage etc. but as they grow older then they will start to hiss at you to try to scare you away. Some do tolerate you handling them but they never will like it and it will cause them unnecessary stress. They are animals that should be admired and not touched. I do have one veiled that loves to be taken out of the cage and sits on my shoulder but this is very rare and he came a abusive home and is not in the best of condition which is probably why he is like this.
Ask as many questions as you want, it is best to know as much as you can before purchasing a chameleon.
