I usually get all of my information on the internet. I don't know of any good pet books, especially ones that are not for dogs. All the information I got from books were pretty vague and very outdated. It's true that internet is full of misinformation, as it is free for all, but you can easily weed those out by looking long enough. Some forums and internet sites can offer really quality and detailed information, and answer questions I didn't even think of before. You can also hear first-hand experiences of people who have the same kind of pet as you and have gone through a lot with them. There are even some veterinarians that answer questions online, and that's really helpful. There is one think I really don't like coming across, though, and that is people posting threads describing a pretty serious sounding wounds and conditions their pet has, and asking what they should do. For those kind of things I would go directly to the vet, no additional information needed.
