After visiting a wolf sanctuary where 30 wolves lived, Youtube user thesadistnationx witnessed something amazing. He unwittingly walked into a pack howling. In their video description, he says that after one wolf howled, it led the 30 other wolves in the sanctuary to howl along.
Imagine being in the middle of a pack of animals coming together. Pretty cool…unless you are afraid of wolves. Not sure they are the friendliest animals, but this is pretty awesome nevertheless.
