I have read about zonata in the wild being already diseased, and nobody is keeping those on a strictly rodent diet, instead they have access to lizards. So my theory may have a hole in it. But Maybe the wild zonata survive the disease and go on living anyway, whereas captive zonata die because they can't get any lizards.

I am willing to experiment if any one would like to give me some zonata! LOL!
