I took this book out for my daughter from the public library and thought it was so cute that I had to buy it for my school library. Cyril is the only squirrel in the park and becomes best friends with Pat, who happens to be a rat, although Cyril doesn’t know this (or perhaps just doesn’t care) even though other animals try to tell him. The two enjoy doing things together, such as playing hide-and-seek and a game called Pigeon Sneak. Together, they are even able to out maneuver Slim, a dog that enjoys chasing them. Finally, a little boy ruins their friendship by outing Pat as rat, causing him to leave the park and his friend. Luckily, after being chased by Slim, Pat and his team of rats save Cyril and Pat moves back to the park. This is just such a sweet story of friendship and how you can be friends with those who might be “different” from you. My only little pet peeve, likely because I’m trying to get my three-year-old to use kinder words, is that “stupid” is a word in the book. Probably not an issue for most, but I just changed it to “silly” when I was reading to my daughter and to classes at my school.
