Perfect for a chameleon because it does not need their glass cage, more wood keeps the heat and humidity. As against a default if terrarium is a chameleon, my case, there must be larger vents, so you drill on it to install a fence around 40x40 but also down. Personally, we bought ventilation grilles trade we installed above and on 2 sides, these vents are screened. But it is the practical side, there is wood so we can tinker with to fix it for us. I recommend it, frankly, light, warm, very good.
