I really don't think it is a good book based on the title. Say what every you want about sav's being easy to tame but for first timers they can be hell on earth. Taming to "household pet" status is not easy and many monitors never get to that level even with experianced handlers. The book is implying like many iguana books that savs are easy to care for and just about anyone can have them.
When it comes to sources for care and the animal in gerneral I research for aleast a month and then evaluate the cost of keeping the animal. I also look at more than one source and see how old the information is. Books about iguana keeping 20 years ago are not going to provide the information needed to keep iguanas as pets that books written 3 years ago will provide. The same is for every species. I also check out other forums and ask a lot of questions to people who keep that species.
I don't get an animal until I have everything completly ready, understand the care and the species from start to finish, and know I can afford to keep it. Taming with reptiles and any animal is like gaining trust and learning a different language at once. You have to learn the body signals in order to fully understand your animal regardless if it is a leopard gecko or a retic. The animal must trust you and you have to trust it when it comes to letting it be a "household pet" and to trust it around other people.
