Oh gosh where do I start?
I have a PDF version of that book plus all the extra free supplements and they are awful! Absolutely awful. The information is incorrect, it is outdated and the photos are stolen.
Here are some quotes for your enjoyment:
Aquarium:
The aquarium must be large enough for a full sized chameleon. However if you are purchasing a hatchling then you either need to portion off a small section of the tank or purchase an additional smaller container for temporary use.
(While I realize that screen cages are not crucial to keep a chameleon, there is no mention of other caging options. None)
Your first goal is to immediately introduce your hatchling to an adult sized aquarium. This must be done as soon as possible. Now the trick is to accessorize only a small portion of this large aquarium so that your hatchling will not venture from this region.
An Appropriate Substrate
Astroturf is your best bet here. Calcium Sand is a close second choice.
Appropriate Supplements
This is essential to the healthy development of chameleon. You will need a calcium and multivitamin.
(Cool, recommending supplements. No indication of what kind, or how often. None)
Lighting
Chameleons require exactly 12 hours of light per day. This allows them to properly produce a vitamin that’s critical to properly absorb calcium (Vitamin D3).
(No mention that it needs to be a specific UVB emitting light. Cool)
Temperatures
It’s extremely important to ensure your chameleon has a basking spot on one side of the aquarium that is around 90-105 degrees.
(Mmm. Toasty)
Do Chameleons like to be pet?
Actually they do! Under the chin is a great spot to pet your chameleon.
(I’m not denying that some chameleons are friendly but to equivocally say that they are domesticated and like to be petted is quite another thing)

Please do not support that author or claim that book is in any way a proper guide for keeping chameleons.
