Reading and Cats are 2 of my favorite things.
These are my recommendations :
Grades 2 to 4:
“Bad Kitty” books are good books for kids in this age group. The author, Nick Bruel, always tells a good story about a cat that gets into trouble. Inside there are also some helpful tips for cats. In Bad Kitty Takes A Bath his owner tries to give him a bath with very funny consequences.
Grades 4 to 6:
The Warriors series has many books and are excellent for good readers that like cats. There are so many books in the series that you could read them for a whole year! They revolve around 4 clans of cats, but mostly Thunder Clan. The first book is called Into The Wild. You should read the books in order.
