The Physique of a Felisian

Felisians are descended from the cat-like creatures native to their home-planet, and still retain many physical features from their ancestors. A felisian's head is recognisably that of a cat, though much larger than you might expect. Their fur comes in several different colours, though not as many as that of the domestic cats of our universe. Interestingly, unlike humans, they have never fought any racially motivated wars, or committed any form of persecution based on fur-type. Fur colour is thought of in a similar way to that in which we think of hair colour, and it is not necessarily hereditary, so two black-furred parents could birth a litter including ginger kithis (A "kitha" being the correct term for a felisian cub). The possible fur colours are black, brown, ginger, grey, and, perhaps strangely, green. White is also a possibility, but it is rare. Felisians, unlike their feline ancestors, have an opposable thumb in addition to their three fingers, which is the feature that set them apart from their non-tool-using cousins in the evolutionary past. Their feet are very much like large cat paws, but their hands have evolved into a more human form, though they still have small pads. Indeed, felisians can stand either erect, like a human, or on all-fours, like a cat. It is generally considered polite to stand erect in company, but in private most felisians assume their more comfortable quadrupedal posture. This is why the Stardrifters were designed in the way they were, and the computers are accessed in the way they are.
