Pillars of Eternity II: Deadfire pets

Pets are a special type of follower. They can't be attacked or targeted, and will follow the player character around. In, each pet provides the following:
 * A unique bonus, applied only to the player. In most cases this is not shown under the current effects.
 * A unique bonus, applied to all party members via a passive ability Pet Party Wide Effect given to the player (with exception of Nebula).

While all party members have a pet slot, by default only the player can have a pet equipped. Other characters will have this slot locked. Using the Berath's Blessing ...Can I Pet Him Anyway? will unlock the pet slot for Edér, otherwise you can use the console command (cheat)  to unlock the pet slot for all party members.

Backer pets
Many of the pets in the game were the result of the $500 "Name a Pet" tier, available to backers during the Fig campaign. This allowed eligible backers to name a dog, cat, or pig, picking its color from a list of existing textures as well as its effects. All backer pets cost in-game.

Additionally, there was a $2,000 "Create a Super Pet" tier, which allowed backers to select any creature in the game (or a custom one), as well as the buffs it would provide. There are four super pets: Animancy Cat, Eviee, Grog, and Xopn'aua, each providing more substantial effects than regular backer tier pets. All super pets cost in-game.

Critter cleaver
Patch 4.0 introduced a new mechanic to the game called the "Critter Cleaver". Located in The Dark Cupboard in Periki's Overlook, this gruesome machine allows willing players to mix-and-match pet bonuses and appearances, creating new pets with the appearance of one, and the bonus of another. This comes at a cost however, both monetarily and consciencely. After updating the game, the Watcher will receive a missive "Try the Critter Cleaver!" on approach to Neketaka. This document offers a brief explanation from its owner as to the machine's use and origin.
