I didn't know under which topic to put this... it is kind of funny I guess
hehe. Sometimes when one of the pack members has gone somewhere, Vila gets really sad and walks back and forth and moans a bit. Then I put on a youtube clip of wolves howling and Vila starts what seems like crying and calling out for her pack member. It isn't simply responding to the video because she doesn't howl if everyone is home, even if I put on the clip really loud, hehe. The last howl (no. 3) was so loud that even the glass windows were shaking a bit!
