Scratching

• Cats like the texture of cardboard, especially when the edges are put together to form a cardboard cat scratcher. It is similar in texture to wood and the spaces between the cardboard sides allow cats to sink their claws into it to stretch and to scratch.
  
  

Play

• Cardboard comes in various shapes and sizes that provide ample opportunity for exploratory play. Human owners add even more interest when they create cardboard houses for their cats.
  
  

Hiding Opportunity

• Cardboard boxes provide opportunities for the cat to hide. They enable cats to watch without being seen.
  
  

Ambush Opportunity

• In multiple-cat households, one cat can wait in the dark recesses of a cardboard box for another cat to walk across the opening to pounce on the other cat. In single-cat households, the cat can ambush the legs and feet of unsuspecting family members.
  
  

Vertical Space

• Cardboard in the shape of boxes also provides vertical space for cats. They enjoy jumping up and surveying their domain from a higher vantage point.
