The Fellpool, also referred to as the Felinefolk, are a species in the Star Ocean series. They are a humanoid race that descended from felines. Fellpools bear an astonishing resemblance to Earthlings, the only physical difference being the tails that extend from their posteriors and the greater variety of ear shapes. The Fellpool are also extremely curious. They have exceptionally strong senses of smell and hearing, as well as powerful night vision. Fellpool are the racial majority on planet Roak, and can be rarely found on the planet Expel, and are ancestors to the Expellian race.
A branch of this species is the Lesser Fellpool, or Ur-Felinefolk, which is a less developed type of Fellpool, being an intermediate between a cat and a human. However, unlike the Fellpool, the Lesser Fellpool have the ability to transform into cats.
