Most sick reptile pets are caused by poor temperature control. Enteritis and pneumonia are mostly related to temperature. The High/Low temperature alarm function can more effectively remind you to notice temperature changes in your pet's living environment. In addition, too high humidity will lead to the growth of bacteria in the breeding tank, too low humidity will cause digestion and absorption dysfunction, nutrient molting, and ultimately affect normal development. No matter what kind of crawling pets you keep, you need to pay attention to the temperature and humidity they adapt to.
