The red fox may look like a small dog but its build is much lighter. Among other things it has lighter limb bones and a stomach half the size of a dog of the same build. Because of its smaller stomach it must eat often. When it catches prey it often hides some of it in one of many small caches, buried just enough to hide it from thieves but not so deep that it cannot be found by the one who hid it. It usually leaves only a small amount of food in each cache so that it can't lose it all in one blow should someone find his secret storehouse. While some of it does get stolen, and some caches are never found again, overall the red fox has a great memory when it comes to remembering where his food is hiding.
