This is a very imaginative book and I enjoyed reading it. I liked the illustrations because everything looks very realistic and familiar. The Professor looks comforting and Boing Boing is very futuristic. The story is about when Boing Boing and Daniel go to a Zoo and rescue a little girl from a lion's cage. Boing Boing is a bionic cat who is bionic because Daniel is allergic to normal cats. He was invented by Professor George. I liked the bit at the front where it explains all Boing Boing's features. Also the glossary at the back because it makes you understand the story much better. I think that it was good that the animal sounds are exaggerated in the book such as the elephant's trumpet call. I'm now going to read the other Boing Boing books.
