Tells you about things that can go wrong, certain feeding issues, things not to do, etc. Very good book

Pros: Very thorough and informative

Cons: None

This is the first gerbil book I bought when I got my two adults. They turned out to be one of each sex due to a breeder/pet store mistake and I have 5 weaned pups now. I had to scramble online to fine sites that were helpful about what to do in certain situations and how to prepare for the worst (like respiratory infections). I bought a different book online that was much more helpful (author runs abcgerbils.com, which has a lot of great information). Gerbilbreeding.com is another great site, esp. if you're interested in gerbil genetics :)

Pros: Easy to read, lots of photos and charts, great for first time owners

Cons: Not much information for if you are breeding or accidentally breeding
