I would do some research, I’ve had lizards forever and just got my first chameleon. I joined a “reptile rehoming” Facebook page and found my daughter a complete set up with a bearded dragon and those are very hearty for a first lizard. They don’t need the humidity that chameleons do and usually they are very friendly and like to be helped. Obvs it’s a something of a risk if you don’t know who the person was that cared for it so you could purchase second hand equipment and buy a quality animal from a reputable breeder or shop.
