RebYidd – sorry, but there are no domesticated foxes, except those which are raised in cages for their fur. Having a pet fox is illegal in most places, and it’s wise to be careful of the wild ones anyway, since a few of them carry rabies. Foxes are indeed amazing, but if they’re eating your chickens or your cat or turning over your garbage cans, maybe you’d like to admire them from a distance.
The OP should just be happy that they’re not coyotes. Those have moved across Canada (interbreeding with wolves on the way) and are now working their way down the east coast of the US. And they’ll not only eat your cat, they’ll eat that fox, too.
