point being, biology, particuarly genetics, doesn't really recognize "race" in humans. Not what we classify as "Race," anyway.
The closest approximation you can get to a biological definition of race in humans, is the same classification with animal descent: geographic accumulation of common traits.
Though as with humans, dogs, cats, various bird species, the presence or absence of a particular trait or series of traits would not singularly allow for an exact definition of "Race."
....what I'm saying is: either humans and cats have races, or neither do.
