I've noticed that some of the spikes on the back of my Veiled chameleon are starting to look like they are rotting... not sure if that is a good way to put it, but the last time she shed is when that happened. She eats regularly and uses the bathroom. I haven't seen any strange signs out of...
I use the same fogger for my veiled. i find that it helps keep the humidity up, as well as create a small amount of water build up at the end of the hose. I also have a misting machine to, so she is getting plenty of water... but i do still spray down her enclosure 2-3 times a day...
