Feline Hominid

Feline Hominids were bipedal felines.

Big Cat, who resembled a Tiger; Wildcat, who resembled a cougar; and Bobcat of the Hellcats were Feline Hominids from the planet Altaria.(COMIC: Warworld)

Behind the scenes
Free-Fall Warriors does not explicitly state if Altaria is the home planet of Feline Hominids nor does is say of they are a species or a general term for bipedal felines. Cheetah People, Cat-People (Lion-men, Felinoids, Mercenaries of Gin-Seng, Kzinti), Catkind, Sehkmet, Fatkats, Leonians were other groups of sentient bipedal cats.

While not seen in Free-Fall Warriors, Bobcat likely resembled the animal of the same name.
