Felines were a kind of animal that were famous for regulating the numbers of rats and related rodents. Moreover, they were frequently domesticated by different sentient lifeforms. Several species of feline existed, including Tookas, Rada-cats, and Loth-cats. Typically, they possessed pointed ears, whiskers, relatively flat faces featuring subtly projecting muzzles, and small eyes capable of dilation when experiencing fear, excitement, or nervousness. Their fur came in a wide array of colors. The majority of felines featured talons much like birds, elongated mouths, and a pair of slit-like nostrils located beneath their eyes.
