Introduction

An icon of an animal face may appear to the right of the HP bar of a targeted monster. This means the monster has a certain rate to drop a catchable pet. When you mouse over the catchable pet, the mouse arrow changes into a lasso, meaning you can catch it. Left click the mouse button to catch it.
Remember, when you are attacking, you can't catch a pet.
