Caterwauls are semi-intelligent bipedal felines that possess great speed. They are natural predators and use their speed to stalk prey. The caterwaul’s lair is most often a cave littered with sticks, twigs, and leaves, with walls covered in scratch marks where the beast has honed its claws.
A caterwaul is about 6 feet long (or tall if on two legs). It weighs about 250 pounds.
A caterwaul begins combat by utilizing its screech attack. After that, it uses its claw and bite attacks each round. By dropping to all fours, it can increase its movement speed.
