Yes, Vaniji does have hooves, which he gets from his Cloven ancestry. What with his wings, his cloven feet, and his long tail, all he needs is a spiffy pair of horns to make him look the part of a demon. Don't think he wasn't disappointed to miss out on that genetic quirk, he'd have gladly traded in his dinky wings for proper horns if given the option. Many people with the tiny wings that can result from Avian ancestry choose to have them surgically removed, since they can't fly and get in the way a lot of the time.
