i think i bought that book from petco too, we were using it, but then we found this site with actual people who seem to know what they are talking about so we decided to stick with your guys advice since a lot of the stuff in there conflicts with the majority of people here say.so im sticking to the advice of people with experience with snakes rather than a book from a place which doesnt even have thermometers or hygrometers in their cages with their snakes for sale.
