Hello, im trying to make a corner shelf and attach ropes to the center underneath so i can attach a wicker basket to make a swinging cat bed for 2. Im having trouble thinking of ways to safely attach the ropes to the shelf making it heavy duty aswell. For the self its self i have a thick chipboard unit i was going to cut and use and for more shelves to but im not sure if it would be heavy duty enough for cats to climb and lay on. If you have any ideas i would appreciate you help. Yours kindly
