Mrs. Ashboro's Cat (movie, 2004)

Wes Merritt and his daughter Natalie (14) get more than they bargained for when they buy an old house that was formerly inhabited by the nice old Mrs. Ashboro and her pet cat, Margaret. When strange things start happening in the house, all fingers point to the presence of Margaret, who died the same day as Mrs. Ashboro. But why has she come back to haunt them?
