Plenum spaces provide two problems if there is ever a fire. First, by necessity plenum spaces are loaded with fresh oxygen. A small, smoldering fire can really take off if it breaks into the plenum space. The second issue is that the air in the plenum space is forced throughout the whole building.
An adult could survive 2 to 3 days without food as long as they have water. You must get some water into him at the very least! With chameleons, they are rather picky about how they eat and drink.ame with food. Once he sees the crickets hopping around and climbing on the branches, that's when he'll get excited and start hunting. Chameleons are very shy at first, so once you offer food and water, I suggest you step away and watch him from around a corner.
Chameleons in general are quick to mature and reproduce, both in the wild and in captivity. In the animal kingdom, this usually correlates with a shorter average life span. Unfortunately, even the healthiest of veiled chameleons rarely live longer than 7 years.
