Heating stone is preferable to certain agamas, basilisks, bearded dragons and water dragons, iguanas, frilled and collared lizards. On the other hand, it is to be avoided for certain species of lizards and for all snakes. It is important to remember that heating stone does not heat the environment; it is used only for the digestion of the reptile. If in doubt, do not hesitate to ask us if the heating stone is right for your reptile.
