Take the second log and lean it against the first at about a 45 degree angle. Use rubber coated wire to fasten them together. Lighting and Heating Maintaining the proper heat and humidity is very important for a reptile's health. We did extensive research and consulted veterinarians when designing our cages. This retains as much heat and humidity as possible, yet allows for some air circulation.
Many people think wire sides are necessary for the pet to get proper air flow.
It is actually not as large a concern because most reptiles move around at a glacial pace. They do not move around a lot like say, a ferret or guinea pig. A reptile spends most of the day sitting in one place. Therefore, they do not need as much air circulation. It is a big misconception that chameleons, for example, need screen sides on their enclosure.
