Most of the wildlife observed today can be traced back to creatures of Earth. In the Orokin Age, organic manipulation was used to modify earth lifeforms to a purpose: war, agriculture, pets. Long after their Orokin masters perished, some of these species managed to survive through adaptation, and can be found roaming in natural environments.

Main article: Kubrow

Kubrows are terrain-restricted melee canine companions. Kubrows behave similarly to NPC allies (i.e. specters) as they will stay within close proximity of the player while fighting alongside them and will enter bleedout states when they are downed, from which they can be revived. Incubated Kubrows have variable permanent traits such as species, height, and eye color, as well as customizable features like fur color and fur pattern. There are currently 6 species of ownable Kubrows, each with different stats and abilities.

Kavats are terrain-restricted melee feline companions similar to Kubrows. They also have different breeds, color palettes, and patterns. There are currently three types of Kavats.
