All I have to say NocensVir, is do your research (which it seems your doing, considering your on here) but MOST important...Just try and have some common sense, Chameleons are not domesticated like dogs and cats. Therefore there aren't much facts about these animals other than the fact that they can be very delicate. Only advise I can give you is, when you are doing your research go based off sites that seem well experienced. ANYONE can give you their opinion about how you SHOULD or SHOULDN'T keep chameleons and I guarantee you on here THERE WILL be people who WILL disagree with other peoples information. For example I've always wanted a chameleon, I finally did my research, and all the info was all different. The pet store I got my chameleon from told me one thing, the people on here told me another...The bottom line is there not all the time. Some like certain things that some don't. Just use your common sense and go based off a experienced owner.
Its like taking home a baby, it doesn't come with a manual. As long as your baby (Chameleon) looks healthy and your attentive to it you should be fine. So don't let anyone intimidate you from getting one. Just do your research before you get one.
Ps. I am no expert...This is just my opinion...Im sure you'll get plenty more on here.
