1. Materials and purchasing location:

1. One wooden board is 28*24*1cm, and two are 43*35*2cm (this should be easy to find)

2. Three PVC pipes with a diameter of 7.5cm and a length of 44cm (you can buy this at a small store that sells building materials and hardware)

3. 60 meters of velvet rope (it’s best to buy more. You can buy this at the store where you buy PVC pipes. If you want better quality, you can go to a famous hemp rope store, but the price is not cheap)

4. Brightly colored cloth (available in any fabric store)

5. 6 round wooden blocks with a diameter of 7cm (as long as they can be stuffed into a PVC pipe) and a thickness of 7cm (if it is not that thick, you can also use 2-3 blocks to glue them together)

6. The amount of sand is about 10-20 kilograms (depending on which house is renovating nearby, go get some *^_^*)

7. 6 screws, preferably 5cm long.

8. 2 bottles of latex (you can buy both when selling PVC pipes)

2. Tools:

Hole opener, electric drill, nail gun, multi-purpose knife, screwdriver

3. Production method:

1. Use a hole opener to drill a hole 7.5cm in diameter and 0.5cm deep in the corner of the 28*24*1cm board. Cut a hole 7.5cm in diameter and 1cm deep in the diagonal corners of a 43*35*2cm board (half the thickness of the board, don't punch through). Another 43*35*2cm board also has the same holes as the previous one, but in the opposite direction. On the back of one of the 43*35*2cm wooden boards, open another 7.5cm, 1cm deep hole at different corners, and then open a large hole in the center of the wooden board with a diameter that a cat can drill through.

2. First pour sand into two of the PVC pipes, use two 7cm thick round wooden blocks to plug the two ends of the PVC pipes with glue, and use an electric drill to drill a small hole (connected) at both ends of the PVC pipes. Punch the wood inside together), drip latex into the small holes, and then insert one end of the rope into the small holes with a long and thin object such as a needle to stick it. Then apply glue on the tube and start wrapping the rope (pay special attention to your hands when wrapping the rope. My dad's hand got 3 big blisters, so it's best to wear threading gloves). The rope must be wrapped tightly, otherwise the cat will The cat was caught easily. When the rope is wrapped around the small hole at the other end of the pipe, use the above method to insert the rope end into the small hole. Note that when wrapping the rope around both ends of the PVC pipe, leave a distance as deep as the opening in the board so that it can be inserted into the board later.
