Temple Cat by Andrew Clements illustrated by Kate Kiesler*

All of his life servants have taken care of the Temple Cat's every need.  He,  however, longs for freedom.  One night he escapes and finds true happiness with a lowly fisherman and his children.
My son and I read this together for his reading.  Again, it was on a the easy side for him, but he enjoyed the delightful plot and the fact it was about a cat!
As we read, we inferred, asked questions and recorded the plot.
I liked how the sweet story exposes young readers to a time period in history.
*Highly recommend.
