I dont see what is wrong with the book???
I actualy own this book, it is very good and it is aimed at people keeping exotic chameleons in South Africa, so there are some good pointers for us concerning breeding and how to deal with the heat, low temps or the little humidity in some parts of the country.
David Hagget is the author and was the only person breeding panthers in S.A aswell as fischers, jacksons and br. thieli I think, he is probably the reason for getting people of S.A so interested in chams.
