The felo is a creature native to the planet of Grenwold.
A six-limbed cat-like being, the felo is one of the few animals known to have an innate aggression towards the spaceborn parasites known as bari.
A normal felo can rip through a bari horde with ease, one or two can quickly remove a light infestation from a small ship.
Bari warriors, on the other hand, slaughter the smaller felo. The pheremones produced by the warriors must do something to the felo, however, as the felo begin their own metamorphosis when on a ship inhabited by warriors, eventually becoming soldier felo, muscular creatures that can take down a warrior with effort.
Felo require food in the form of a small type of fruit found on Grenwold. A small amount of soil is all that is needed for a seed to sprout into a plant that grows these fruit, and the felo will eat when hungry.
The felo also create their own sleeping areas, known as felo domiciles, in corners of rooms.
Unlike bari, felo (including soldier felo) cannot survive the vacuum of space or hostile atmospheres. Any felo in an airlock when it is cycled to one of these will die.
