The pets that the player can adopt on Powerpets are animals that can be found in the real world, from normal cats and dogs to the more endangered species such as tigers and zebras. Each of these pets have their own individual "region" and can be changed to different colours using fur tonics at the Grooming Parlour in Xiang Chung-Shi. On Powerpets, there will be a different week for each animal, on which new backgrounds, profiles, food and toys will be released, and those who own the featured pet also get special benefits in that period of time. As of April 2012, there are a total of 80 pets for players to choose from.

In Powerpets, players can do a variety of things with their pets, such as feeding them, playing with them, increasing their strength or even armouring them so that they can battle and compete in the Powerdome to fulfill quests or a gameplay plot.
