How to build an outdoor cat tunnel

Cat tunnels are a such great way to let your cats safely enjoy the outdoors so they can explore your yard.

- deck planks – pressure treated 2×4 lumber  – deck screws – galvanized fence staples  – wire fencing/pet fencing – drill – hammer – measuring tape – outdoor wood stain – brush for staining – (mineral spirits or turpentine for cleaning the brush) – wirecutter

Materials and Tools needed:

I stained all the wooden pieces before I even started building anything and let it all dry.

1

2

Cut the 2×4 lumber in strips to match up with the width of two deck planks lined up next to each other.

I cut one of the deck planks in half, so I could stagger the pieces which ensures more stability.

3

I needed some extra pieces of wood to add to the tunnel surface because our walkway is on a steep incline/hill and I wanted the cats to have something to hold on to.

4

Now it’s time to assemble the bottom part of the cat tunnels. Layout the 2×4 pieces on the ground and add the planks on top.

5

Then pre-drill the holes where the planks attach to the 2x4s.

6

Use two to three screws to attach each plank end to the 2x4s.

7

When you have one large tunnel walkway, it is time to attach the wire fencing.

8

I trimmed the width of the wire fence with a wire cutter since I didn’t want the tunnel to be too tall

9

Attach the wire fence with the fencing staples and hammer to the one side of the plank.

10

Now turn the planks and fencing around and bend it over the walkway part and hammer in the galvanized fence staples on that side as well.

For this cat tunnel project I chose not to finish the edges of the tunnel with another piece of wood as I did in this photo of my tunnel running along the side of our patio.
