Experts recommend that a heat mat should fit around half of the floor space of the vivarium or enclosure. This means that the reptile has an area to cool off too - a hot and a cold side so that they can manage their own core temperature by moving a little. Many come with a built in thermostat, to monitor the temperature such as the Swell Pro Heat Mat, which is available in four sizes. Or, thermostats are available to buy separately, all at great prices from us here at Swell Reptiles.
Made from safe materials that are highly unlikely to overheat (especially when used with a thermostat), these mats are available in different sizes and heat intensities to allow you to achieve just the right temperature in your reptile's habitat.
