OSRS features numerous pets that you can get from bossing, questing, skilling, and events. Receiving pets can be a lengthy process depending on the difficulty of the task. These pets are the easiest to acquire in OSRS: * Chompy Bird: The Bird can only be killed after completing the Big Chompy Bird Hunting quest. Also, you will need to complete the elite Western Provinces Diary. The bird has a 1/500 drop rate, which is one of the highest among pets. * Cat: If you want to receive a pet as soon as possible, the fastest method is completing Gertrude's Cat quest. After completion, you will have the Cat in your inventory. * King Black Dragon: The easiest boss pet to get is by killing the King Black Dragon. He has a combat level 276, so you will need a decent combat level. Slaying the dragon is very easy as he doesn’t have difficult mechanics. He has a 1/3,000 of dropping a Prince Black Dragon, which is a smaller version of the boss.
