Tia Maria & Mozart
Tia Maria and Mozart like to get into all sorts of mischief in their neighbour's bin. Unfortunately, it all ends rather badly for them in this Canadian thriller which may have been inspired by "Miss Paisley's Cat" (1957) from the "Alfred Hitchcock Presents" TV series.
Victor (Jay Baruchel) was probably lying to Louise (Emily Hampshire) about where he got Balthazar from, but this feline still has the required result.
If you love cats as much as Louise does, you probably shouldn't watch this movie.
