Why Not To Mist At Daytime
If we speak about indoor caging, the most keepers do terrible disservice to chameleons reverting their hydration cycles. This kills the chameleons slower or faster way and cuts a substantial part of their lives.
And what we do to them now when we put them in terrariums?
We put them into a terrarium and let them sit the whole night in the driest air during the whole day cycle at relatively high temperatures (because we do not as a rule simulate the natural night drops of the temperatures) and then at the daytime, we even increase the temperatures (usually to higher levels than in the wild), add a permanent, very hot basking spot and during this, when the temperature is extremely high, we spray the terrarium with water.
The combination of hot air together with high temperature and slow air movement, which is the result of misting in the daytime at high temperatures is one of the best environment in which bacteria and fungi reproduce and as a result respiratory diseases develop because all it is absolutely unnatural.
If you want to be sure, the chameleon has enough water to drink anyway, the best option is a dripper. This does not spoil the environment with too much extra humidity as it is used only locally and amounts of water are little.
In outdoor caging, the situation is more complex, as misting is often used in areas too hot for the chameleons to lower the temperatures for them during hottest periods of the day. It is quite risky too and brings health problems, as we force the animals to live in conditions, which are unnatural for them, but under circumstances, they can survive this and even more reproduce. They however never make longevity records and often die at half of their lifespan or even less.
