Guinea Pig is a cat that can initially be found in the northern part of Falador Park near the border wall. He believes that he is not a cat but in fact a guinea pig. Upon conversing with him using a catspeak amulet (or a cramulet that contains one), the player convinces him that he is indeed a cat. Guinea Pig then agrees to join the player at Het's Oasis where he can be found roaming near the cactus patch in the south-western quadrant of the oasis.
