Oh, and rats aren't on the approved pets list. How *did* Percy get 
permission to bring a rat to school? That one, particular rat.

Elihu's answer:

Maybe because the Weasleys were on close terms with Dumbledore, they got special permission to allow their son to bring a rat of theirs to school. Dumbledore didn't know that this rat is a problem until shortly before Percy graduated.
