My 7 year old son picked this out for me to read a loud to him and his sisters for the local summer reading program, it was a cute enough book for our family who loves having guinea pigs as pets (we've had 4) however I have two words of caution - there is some pranks that go on between two of the 'new' girls and two children who have been at the school a long time, today, the pranks would be called bullying. There is no real discipline for any of the children who misbehave, making it seem like it's okay (it's dangerous for guinea pigs to eat sweets but this action is overlooked) and when the one girl lies to the teacher in order to make a truce between her, her friend and the two other students nothing is done. I will say it did open up a discussion between my three children and I and all of them were like she got away with lying to a teacher. Cute book but I would have liked to see the children learn from their bullying, pranks and lying instead of them being thought of as cute, just being kids, etc.
What do You think about Guinea Pigs Don't Talk (1994)?
