Cardboard Castle Fort

A multi-room hideout built from delivery boxes you already have

Join a few cardboard boxes into a connected fort with doorways and peek-holes. Boxes give cats a sense of security and a lookout for surveying their territory — this turns spare packaging into rich enrichment.

🧺 You will need

  • 2–4 clean cardboard boxes of similar size
  • Packing tape
  • A box cutter or strong scissors
  • A soft blanket or towel (optional)
  • A few treats to encourage exploring

🔧 How to make it

  1. Remove any staples, plastic tape and glossy printed inserts from the boxes.
  2. Arrange the boxes in a row or an L-shape to plan your layout.
  3. Cut archway doorways at floor level between neighbouring boxes so your cat can walk through.
  4. Cut a few paw-sized peek-and-swat holes in the sides for play.
  5. Tape the boxes together firmly so the structure is stable.
  6. Add a blanket in one room and scatter a few treats inside to invite the first exploration.

💡 Tips

Position the fort near a window so one room doubles as a bird-watching lookout. Rebuild the layout every couple of weeks — a new floor plan renews the novelty for free. Cutting doorways at floor level lets even senior or arthritic cats pass through comfortably.

Safety: Remove all tape residue, staples and heavily inked liners, which can be a choking or chewing hazard. Supervise cats who habitually chew and swallow cardboard, and replace the fort once it becomes soft or damp.

📝 Notes

Completely free — it reuses delivery boxes destined for recycling. Break it down and recycle when it wears out, then build a fresh one.
