Pet

A pet is a non-combat NPC loyal to a player that is generally obtained from monster drops. Some pets must be raised to maturity by having it follow them, such as a cat. Pets can also be interacted with. Most pets do not serve a purpose other than aesthetics, as most pets are very rare drops from certain bosses and thus are often considered prestigious. A player may only have one pet following them at one time. Upon receiving a pet, the same sound as the strange plant random event will be heard.

Pets may be stored in the bank or inventory, and will follow the player when dropped. Players can store up to 35 pets in the Menagerie of a player-owned house (with the highest-level pet houses).

Unlike other pets, kittens must be stroked and fed regularly or they will run away. Once they reach adult stage, they no longer need to be fed.

Boss pets
These pets usually resemble bosses that are obtained as a secondary drop from them, or are obtained by other means.

Skilling pets
These pets are obtained by training a specific skill, where the chance of obtaining one is based on the player's level and the rate in which the resource is gathered, if applicable.

For all drop rates, subtract your level in that skill multiplied by 25.

Other
These pets are obtained either through quests or other means. EHP to get pet (listed in order of least time needed to most)
