I am wanting to get a Chameleon, I will not say that I am an expert, but my Iguana is fully grown ( 5.5ft) and I've had her about 6 years, so I am not totally unfamiliar.
Here's the plan, obtain, or create a small mesh cage. standard UVB light on a timer. Heat source, on a thermostat. Now, I was planning on using an ultrasonic fogger on top of the cage, that would allow the fog to fall from the top of the cage.
Here are the questions
1. Will the ultrasonic fogger work instead of a misting system?
2. Are there any economical ways to control the heating, and fogger electronically?
3. Should I buy one from a local pet shop not knowing how well it was taken care of, or buy from a well known breeder and have it shipped in?
4. I saw one today in PETCO, and it looked kinda small (3 inches) how big should they be to ensure I am getting a healthy one?
