Kilner, Dorothy: THE LIFE AND PERAMBULATIONS OF A MOUSE (1783-1784). v1, 21 Jan 2008
 

From Amazon.com:

This very interesting and charming narrative chronicles the life of a mouse. All the animals have been invested with a unique persona. The work is made unique by the fact that the attitudes, feelings and thoughts of the animal are presented by an animal itself. Interspersed with moral lessons on how to treat the weak, this is a brilliant work.
