Anyone that owns a cat knows the box obsession that cats instinctively possess. Big, Small, Collapsed...hell, even just a piece a cardboard. Its really quite adorable. My kitty Turtles loves to munch on them for goodness sakes,as do others I found out in my search of box kitties. Hail to the Cardboard Box...Cats sure do appreciate the simple things in life...we should do the same.
