They are brothers which Ive adopted from a good friend of my husband.
The black one is Jojo and he is under my brothers's care at the moment. His name was Black Pearl (yes, he was named after the ship in Pirates of Caribbean movie)before my mother changed his name to Jojo (based to some cartoon character).
Jack is the grey one. He is mischief, cuddly and unpredictable (just like Captain Jack Sparrow).
