Cardboard Box Ball Pit

A shallow box loosely filled with lightweight balls for batting, digging and diving

A shallow cardboard box part-filled with light plastic balls turns into a feline ball pit — a satisfying place to dig, bat scattering balls and pounce, especially good for energetic indoor cats.

🧺 You will need

  • A shallow, sturdy cardboard box with low sides
  • A handful of lightweight cat-safe balls (plastic ball-pit balls or ping-pong balls)
  • A few treats or a pinch of catnip (optional)
  • Scissors or a craft knife

🔧 How to make it

  1. Choose a box with sides low enough for your cat to step in and out of easily.
  2. Trim any tall flaps down and tape any staples or rough edges so nothing can scratch.
  3. Scatter a single layer of light balls across the bottom — enough to move around, not so many they pack tight.
  4. Hide a treat or a pinch of catnip among the balls to spark the first dig.
  5. Let your cat discover it and refresh the treats now and then to keep it interesting.

💡 Tips

  • Use balls too big to swallow — ping-pong balls or larger.
  • A slightly bigger box lets two cats play without squabbling.
Safety: Only use balls that are too large to be swallowed or chewed apart, and check them regularly for cracks. Supervise nervous cats at first so a rolling ball does not startle them into knocking the box over.

📝 Notes

The scattering, unpredictable movement of the balls mimics fleeing prey, giving indoor cats a burst of chase-and-pounce exercise from materials most homes already have.
