A two-headed cat box is an Empty monster box containing a Two-headed cat. Making the box will result in the player gaining 30 Monstercrafting xp and releasing it will give 0.7 xp. A two-headed cat box can be created by using two cat's heads and 30 Monster fragments on an Empty monster box while wearing a Crafting necklace. After releasing the box in a Player-owned house Dungeon, a Two-headed cat will appear and attack the player straight away regardless of the players level, so the player must be ready.
