Meet Batman. Another super sweet sibling of Vader. You can find him on his cat tree or doing sprints up and down the hallway.
He started out as a stray but was quickly brought into his foster home with his two brothers to find the safe life he needed.
Batman would be happy to have a friend to play with and is not bonded to his two brothers. Of course, he would not argue with his brother Zorro or Vader accompanying him to a forever home.
