What non aesthetic or behavioral differences would comprise a cat person rather than a regular one? Stronger ligaments in the legs for leaping? Extra facial neurons to fire when the whiskers (and those weird eyebrow whiskers let's not forget) will detect things? Would their more limber skeletal structure and musculature allow them flexibility at the cost of steadfastness? That last one would be a serious issue for anyone who was seeking to create cat people who could lick their own butthole like a real cat
