I've got livestock, and my area is known for wildfires, so my plan has always been to just open all the gates and unfortunately let the goats, donkeys, and chickens fend for themselves. I have multiple parrots and two big dogs, and emergency carriers and cages for each. The tropical fish and snails would unfortunately probably perish, unless I had enough warning to bag them. I have a truck with a camper shell, so probably all critters would go in there and we'd be off to wherever we had to be off to.
