Because they evolved from early mongoose or mongoose relatives that arrived in North America due to the land bridge that connected from Siberia to Alaska during the Oligocene period. They then evolved into the Cetofelis, then Lutonsotherium, then Homodon, and finally Dylanuses. Their DNA is very much similar to hyenas and mongooses, which is why they're known to be their relatives. :)
