Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to make a cat closet [title] Purchase four pieces of thick wood. [step] Either have the pieces cut into the same-sized squares at the hardware store or be able to do this at home. ( the squares should be large enough to form a little closet enclosure for the cat; take along measurements.

Ending1: ) if you're not finding the right size square, these will suffice. You'll want the pieces to be 4 feet (1.6 m) by 4 feet (1.2 m). Ending2: ) some people even make regular nail separators using wooden boards. These boards are just like hangers, as they are spaced evenly. Ending3: ) [title] Purchase a piece of plyboard or other thin, strong board. [step] It should be as high as one of the squares. Ending4: ) if this is your first time making your own cat wardrobe, do not make the pieces yourself--purchase 1 medium sized piece of wood. Measure out 2.5 feet and set aside.
