How to Make a Cat Trap Out of Cardboard


Cats can be very stubborn creatures, often refusing to come when called or go where you want them to. If you need to trap your cat for any reason, whether it’s to give them medication or transport them somewhere, a simple cardboard box trap is an easy and effective solution. In this article, I’ll walk you through the full step-by-step process of making a cat trap out of cardboard.

What You’ll Need

To make your cardboard cat trap, you’ll need the following materials:

  • Cardboard box – Find a box that is big enough for your cat to fit inside, but not too big. A standard copy paper box or small appliance box works well.

  • Scissors or box cutter – To cut an opening in the box.

  • Duct tape – To reinforce the edges of the cut opening.

  • Bait – Cat treats, food, or a toy to lure your cat into the box.

Cutting the Box

The first step is to modify your cardboard box to make it into a trap. Here’s how:

1. Cut an Opening on One Side

  • Carefully use the scissors or box cutter to cut a opening on one side of the box.
  • The opening should be big enough for your cat to fit through. An oval or square shape about 8-10 inches wide works for most cats.

2. Reinforce the Edges

  • Take duct tape and reinforce the edges of the opening you cut so they don’t fray or rip when the cat goes inside.
  • Apply tape all the way around the cut edges to strengthen them.

3. Create a Door Flap

  • On the opposite side of the box from the opening, use scissors to cut a flap about 5 inches tall and as wide as the box.
  • Only cut 3 sides so the flap can swing open inward like a door.
  • Again, apply duct tape around the edges to reinforce this door flap. It will swing shut after the cat enters the trap.

Baiting the Trap

Now that your trap is ready, you need to lure your cat inside. Here are some effective bait ideas:

  • Cat treats – Place some irresistible treats just inside the trap opening. Trail them further inside the box to entice the cat in.

  • Food – A bowl of wet cat food or a can of tuna works well. Place it at the back of the box.

  • Cat toys – Throw a toy inside the box to spark their curiosity and interest.

  • Catnip – Sprinkle some catnip into the box or rub it around the opening. Most cats love catnip!

Trapping the Cat

When it’s time to trap your cat, choose an area your cat frequents, like where their food is kept. Follow these steps:

  • Set the baited trap on the floor and prop open the door flap.
  • Sit and wait nearby quietly. Don’t make any noise to scare the cat off.
  • When the cat enters the trap to get the bait, they will push through the door flap.
  • The flap will swing shut behind them, securing the cat inside!
  • Quickly close the trap and transport the cat wherever needed.

Be patient, it may take a few tries for the cat to get comfortable entering the trap. But the irresistible bait will eventually entice them inside!


  • Familiarize the cat with the trap beforehand by leaving it unset with treats inside. This gets them used to going in.

  • Use their favorite food or treats they can’t refuse as bait.

  • Make sure the trap is sturdy by reinforcing with tape so it doesn’t collapse when they enter.

  • Be slow and gentle when moving the trap with the cat inside to avoid frightening them.

  • Only keep the cat in the trap for short periods to avoid injury or escape.


Constructing a simple cardboard box cat trap is an easy project using materials you probably already have at home. With some strategic bait and a bit of patience, you’ll be able to successfully and humanely trap your cat for any situation requiring it. Just follow the instructions to modify a box with a cut opening, tempting bait, and swinging door. Before you know it, your cat will be caught in the trap and ready for safe transport!
