I would have given the book a lower rating but it was only bad because it was so bland. The author assumes that the reader is a seven-year-old and about 20% of the book is baby-talk. It doesn't go into much detail about training. In fact, "The Hamster Handbook" by Patricia Bartlett (also sold at amazon) goes into as much detail about training a hamster. This book doesn't include much other information about hamsters other than obvious things and is mostly vague. I don't recommend this book, but highly recommend "the Hamster Handbook."
