 It's a widely known fact that cats love boxes. To them, no toy in the world, no matter how expensive or fancy it may be, compares to a simple cardboard box. It's a phenomenon that baffles most cat owners, especially when they've just purchased a great new bed or cool toy, and their cat seems to prefer the packaging it came in. Cats get comfort and security from enclosed spaces, which is why they love spending time in cardboard boxes. Cats use boxes as hiding places where predators can't sneak up on them from the side or behind. If your cat is in a box, any intruders like prey, humans or other pets have to come directly into their field of vision, meaning nothing can surprise them.
