I really like animals and my favorite is a guinea pig, so I thought I would like this book. I liked the story because it was funny. For example, when Jeniusí dad said that he would eat his water bottle, if Jenius opened the gate. I liked how Judy was determined to teach Jenius those tricks. When you are determined, you can do whatever you put your mind to, even if people donít believe you.
I would recommend this book because the story is hilarious and the guinea pig makes it very cute as well. If you like animals and especially guinea pigs, you might like this book too. I would give this book five stars.
