Lizards are cold-blooded so you need to provide them with an enclosure that is climate controlled. The climate is controlled with lighting. Lights provide illumination so you can see your pet but also provide heat. To best simulate natural conditions you also need to provide a dark, nighttime period for your lizard. However, you still need to provide heat so you will need to invest in heat lamps that don’t provide illumination. Research your particular type of lizard and their precise heating and lighting needs. Monitor the temperature carefully. Eliminate any hot spots such as a hot rock or steamy water that could injure your pet. Keep a barrier between the lighting and your lizard so it cannot accidently touch a hot lamp and get burned. And check that the enclosure is evenly heated but with shaded areas for a respite from the heat. For more information, contact your licensed Sugar Land TX vet.
