You’re thinking like a person; think cat instead.

Basically a human on all fours; the legs as long as the arms, the hand much smaller than it should be, the fingers ending in nubs; the body like an extremely emaciated and stretched out baby’s body, with ribs visible; a face with an elongated mouth and nose kind of like a Gelfling, with cleft lips; based on what the cat thinks a felinomorphised human ought to look like, it might have a long tail of just skin (and cat messageboards probably go into long debates about tail vs no tail). Also, whether the specimen is male or female, no breasts of any kind, only nipples. No fur, also no cat ears either (people don’t put human ears on furries for example), normal human ears instead. They would probably call them ‘skinnies’, or ‘fleshies’.
