- 2-by-4 wood stud
- Hammer and nails
- 12-inch round cardboard concrete form
- Sisal rope
- Heavy-duty staple gun
- Heavy-duty staples
Instructions
Open the step ladder and stand it up as if you were going to climb the ladder. (See References 1 for all steps.)
Use a tape measure to measure the length from the front legs of the ladder to the back legs where they touch the floor. Make a note of the measurement.
Cut the wood stud (or have it cut when you buy it) into two pieces, each matching the measurement recorded.
Nail one of the wooden studs to the right front leg and right rear leg of the ladder. Repeat this with the left side. Once the studs are attached, the ladder should look like it is wearing skis.
Use the concrete form to make a tunnel for the cat tree. Choose how long you want the tunnel to be, then have the form cut to length. Place the form onto the wood studs (between the legs of the ladder) and nail it on to secure it.
Wrap sisal rope tightly around each leg and step of the ladder and tightly around the tunnel and wood studs attached to the ladder. Attach the rope to the structure using heavy-duty staples.
