Nanook called a school bus in Worcester home for more than five years, according to a posting by International Animal Rescue in Shrewsbury on Petfinder.com.
But Nanook had clearly been a house cat at one time. She is about six, and is living with a foster family with three other cats. She doesn't "like" them, says the foster parent, but doesn't fight with them.
Nanook could use a forever home.
