Vulov eggs are fuzzy and warm. They vibrate slightly when held.
A Vulov's ears are incredibly sensitive, sensitive enough to be able to pick up the heartbeat of anyone standing within a 10ft radius. This means that they tend to be a rather solitary species with only bonded pairs remaining together. Vulovs will almost always avoid other species entirely. Rarely a Vulov will be seen in the company of another creature. Fokelore says that these cases are because the sound of the other creature's heart is a soothing melody to the Vulov.
