Kit

Kit is a baby red fox that can be acquired by an adopted child as a pet in.

If the Dragonborn has adopted Runa Fair-Shield, Sofie and/or Lucia, any one of them can bring the fox home and ask to keep it as a pet. If the child is allowed to keep Kit, there will be no required upkeep.

Trivia

 * The child who owns Kit never mentions his/her name, and it isn't shown when looked at either. It only shows after the animal has died.
 * If a child is allowed to keep Kit, one can't get the fox to leave at any time. The only way to get rid of the pet is to kill it, (unless a child kills it by accident), but that will result in the children hating and refusing to talk to the player.
