Anyone who is a cat lover will find this interesting to read although if you are familiar with many cats you will learn little that is new. I also only gave it three stars because I was disappointed at the lack of pictures, and the sketches were quite poor. The pictures on the front and back cover are the best.
Anyone with a cat recognises an individual's call for a certain type of food or affection, so the pages on that subject aren't relevant although are fun to read. For example our neighbour's cat Tigger has a specific meow for milk and another visitor, Popeye, has a very distinctive "let me in" call.
We all know that cats like to play, some like solitude, some want to be with you all the time, have their favourite diet, enjoy variety, and so on.
So overall you will not learn much from this book if you are already very familiar with cats, but it is nevertheless entertaining to read.
