When fostering kittens, it’s a great idea to have toys that you can disinfect or, better yet, recycle and throw away after each batch of kittens you care for. One such item is a box fort. With it, the kittens have their own play fort, and you don’t have to worry about spreading germs to new kittens or your resident cats.

Kittens love to climb all over these box forts, and the best part is that you can create unending combinations and unique designs they’ll love.

Here are some basic guidelines for making a safe and sturdy kitten fort.


  • To construct the fort, arrange boxes next to each other, turned on their sides, with the openings turned toward each other.
  • Use packing tape rather than duct tape (which contains reinforcing string kittens love to chew).
  • Use your largest or widest boxes at the bottom for stability, and never stack more than 32 inches high to prevent the fort from tipping over.
  • There should be at least two holes in each box for kittens to run through. When wild kittens get romping, this ensures that no one can get cornered with no exit. No cat fights!
  • Make sure you can reach the innermost portions of the boxes. Kittens are amazing hiders and will love burrowing inside as deep as they can go.
  • Cut large connecting holes between boxes; this way you do not have to perfectly line them up but cut small holes for kittens to stick their paws through for playtime.
  • Stock the inside with cuddly blankets and toys. You might even include a catnip room — if you dare!
