Make a hammock for your cat out of string! Get a wood bar, cut the bar into two equal pieces for the sides of the hammock, and drill a hole near either end of either piece. Thread a piece of sturdy cord through each hole on one bar, knot the ends of the string together, and repeat the process with the other wood bar. Attach a piece of cord through one hole of one bar, macrame the cord into a thick rope, and knot the end of the rope to the matching hole in the other bar. Repeat the process to macrame a rope between the remaining two bar holes. Tie colorful cords along one bar, weave the cords together, and knot the ends to the other bar. Attach lanyard clips to the bar straps to hang the hammock under a chair.
