Feels like an apocalyptic, or extreme weather scenario. Like instead of hurricane season there is fox mating season.
Whenever high concentrations of fox mating pheromones are detected in the air, alarms are sounded through all of the meteorology departments and then you have news channels reporting of the fox movements with satellite images.
Grocery shops are stocked in advanced based on predictions, and everyone's homes are reinforcedwith magic nullifying talismans and steel doors. The first to go are the destitutes and the foolish. People who were too careless to prepare in time, or those who couldn't. They will disappear first, giving the first signals of the fox vanguard.
Then there comes the point where nobody's safe outside. You hear carnage outside: Scratching, moaning and screaming. Better hope you stock well on food. Some might even feel tempted to open the doors to the creatures, in which case, that part of town will be deemed inhospitable until the foxes take back their spoils back to their ever expanding forest villages.
Every year consists of a fight to regain territory from the foxes. Lost in the winter, regained in the summer. Cities expand and contract through the year, depending on what places on the outskirts could face the fox menace better.
