Stop in for a cup of coffee

We have a pair of foxes living in our woods. The slope we rocked last week we put down weed paper first about 40 yards long by 20 yards wide on a 25% slope.
I looked out early the next morning and they were both running up and down the paper rolling on it having a great time.
They have been here since we moved in a year ago as has the rabbits.
I thought for sure the foxes would have eaten them all by now.
Must be a lot of rodents available?
They are more Herbivore then Carnivore.
They do like dog food thought.
They compete with the ground hogs here for Carrots, Apple's, corn etc.
They don't seem to bother the other animals. Kind of skittish actually.
