It's been a week since we acquired Squeak, a very energetic abt. 12 week old kitten. Dusty, our resident spoiled 6 yr. old isn't very accepting. Squeak wants so much to play with Dusty, but Dusty will hiss and swat if Squeak gets too close. Will Dusty ever accept her as a friend? Or is she just too old to accept a baby sister?
