The tortoises readily climb onto these low platforms. A similar heating box can be made from 12 or 16 inch wide Flexwatt panels. If the cage floor is thin enough to allow sufficient heat transfer a heating devise can be placed directly under the cage. As a precaution I have developed ingenious ways of protecting any electrical cords located inside the pens. Unfortunately, I do not have enough space to describe these marvelous devices in the scope of this article.
Water is provided by one of several ways.
A container large enough for the tortoise to crawl into and soak may be left in the pen at all times. However, the tortoise is certain to crawl in and foul the water as soon as you replace the fouled water with clean. Then, the tortoise will crawl out and drip water all over your substrate making a general mess. A hidden hazard with this method is that a clumsy tortoise may tip over in the water bowl and drown. An alternative method is to use a small bowl that may be kept full of clean water at all times.
