Please inspite of your desire to do this, please consider something like a bearded dragon or Gecko's. Horned lizards take alot of very special care to be taken care of in captivity. Ants are their primary food, of which scat analysis is 90 percent or more. Your idea, not being informed about Horned Lizards is definately a detrimental idea. If you live in California these are protected, therefore you would need special permits to even have these. If your looking for a lizard, then a bearded dragon by all means would be an excellent choice because they are omniverous and will eat anything. Although Horned lizards do eat crickets, crickets are a harbinger of disease as well as they do not provide the proper nutrition. Based only on your e-mail, and with all do respect to your experience, because of your description and question, please do not, please do not!! Use a Horned Lizard for this, you will certianly doom them to a slow but certian demise. You wanted an opinion, you've got mine.......a Horned Lizard would be a bad choice when one considers all the options in the lizard rehlm that is available for purchase.
