Nicole Kidman has shared a throwback snap from the 1999 film Practical Magic in celebration of International Cat Day.
In the picture, the actress, in character as witch Gillian, cradles a black cat.
Taylor Swift embraced the celebration by sharing reams of photos and videos of her cats, Meredith and Olivia, in a variety of odd poses, including on top of a Scrabble board and flat on their backs.
In one picture she compared Olivia to a baby seal because of the way she lies on her back.
She also compared Olivia to a superhero and a goalkeeper for her unusual positions.
Swift also described Meredith as a “spelling champion” as she was sprawled out on a Scrabble board.
Swift later wished her followers a happy International Cat Day, from both herself and “the ladies”.
Swift’s cats are named after two of the singer’s favourite characters on television – Meredith Grey from Grey’s Anatomy and Olivia Benson from Law & Order: SVU.
