@rvbuilderJust a couple of thoughts.
First, Eric Wolf's thought that the Goddess looks more like an angel from human mythology than a dizyntk, but the dizyntk don't seem to think she's strange. That feels more like they'll have similar features to humans except where noted.
Second, is the comment in the prologue for book 2 about their fur. They don't have a fur coat the same with that a terrestrial cat does, or a Kzin for that matter. Again, that feels like it makes them more 'human' looking, at least to me.
Their teeth are sharp. I don't know about incisors but I'd imagine they're elongated to a degree.
The one place I remember them being described as looking feline was part of the Protectorate's propaganda, though I might be missing other places.
