  and hyenas shall stay in the abandoned/ruined houses.
  The owls shall live there
  and wild goats shall wander around there.” (Source: Kupsabiny Back Translation)
• Newari: “But animals that live in the desert will take rest there.
  Their houses will be filled with little jackals.
  Owls will make their nests there.
  Wild female goats will prance and play there.” (Source: Newari Back Translation)
