He must have thought it was feeding time at the Lambert Buffet.
With the Ducks, Bunnies, Squirrels, Chipmunks and countless birds. But no, he decided to stock and chase one of the stray cats.
Well as the story unfold, the cat was likely stocking a chipmunk or a bird (both were next to each other) and the Fox was stocking the same pray and he tried to chase the Cat away. He did not get the Cat, had a break after the chase. Moments later I got to see him leave peacefully to continue to look for breakfast.
