Wars Fought By Enemies Bring The Unlikeliest Of Allies

Random thought I had while ready a few stories. I probably won't be as good as them but I can try.

War between the furries and humanity has left most of humanity gone. The last bastion of humanity is considered a myth by most furries while others believe that there are still humans alive. Are they alive? That's what the military wants to find out with the war being over. However, a new threat has appeared at a furry town. Nobody knows where this new threat came from. What is this new threat? Will the furry military find any remaining humans?
