Symbolism:

Since the times of the plague in the 14th-century rats have been symbolic of uncleanliness and impurity. Their quiet nature often has connotations of sneakiness. Note that Pettigrew does not become a snake, who have largely the same symbolism as rats. This is good evidence that he was not a Slytherin at school. Also, rat is slang for snitch or informant, and, in his later life, Pettigrew did indeed inform Voldemort where the Potters were hiding.
