Step 1: Shopping List
2) Wooden dowel 1/2 inch thick, I got a standard length dowel from Home Depot and then cut it in half.
3) Wooden board, I got mine in the craft wood section they have 2 foot boards that are 12" x 1" thick, have it cut in half in the lumber area.
4) Cabinet knob, I got mine at you guested it Home Depot you can basically use any knob with a hole in the top.
Optional) Home Depot has free carpet squares samples in the flooring department, cats love to scratch at carpet.
Step 2: Fun With Cardboard
I decided to cut them in 4x4 squares using a paper cutter, you could probably just as easily a utility knife but it probably won't be as exact.
I've been drilled a hole in the middle of square with my drill press. Caution make sure to use all safety measures when using a drill press because the cardboard can catch or get very hot and start to smoke.
Step 3: Drilling the Base and Attach the Pole.
I drilled a small hole in the center of the partially drilled board so that a screw could attached to the bottom of the dowel from the bottom.
Optionally, this is the point where I would fasten your carpet squares to the top of the board you cut all the way through, I used industrial double-sided tape you could probably glue them down as well. I then cut the hole out in the center of the board with my utility knife.
Inserted the dowel through both boards and screwed it in from the bottom I put an extra couple screws just so the boards wouldn't shift.
Step 4: Cardboard the Pole
