I think that whatever race Nekomatas mate with, their kids with be full Nekomatas, Koneko and Kuroka's father was human but they were never cosidered as "half-human", especially since female Nekomatas typically mate with humans.

Even their children in Ex didn't seem to display any Devil or Dragon features.
