I don't think there are any herp shops near Agoura Hills, but there are some great ones an hour away. Dragon's Den Herp (dragonsdenherp.com), Prehistoric Pets (prehistoricpets.com), and Amazon Reptile Center (amazonreptile.com) are a few. And there are multiple breeders scattered around so cal. If you are here at December 13-14, there's a reptile show down in Pomona. Hope I helped a little
