Here's a Good Thing for your cat: a homemade scratcher that you can hang on a door knob, mount on a wall, or even place on the floor.

Tools and Materials
Wooden plank (we used poplar) that is 1/2-inch thick, 6 inches wide, and 39 inches long

Carpet remnant (ideally from the room in which you will use the cat scratcher), cut to the length and width of the wood plank

Wood glue
Weights (canned food works well)
Measuring tape
Pencil
Drill with 2-inch hole saw attachment
3/4-inch-wide lattice
Finish nails
Paint (to match the door, if possible)
Paintbrush
Optional: heavy-duty Velcro, catnip

Door Cat Scratcher How-To
1. Glue remnant to board with wood glue. Place assembled board and remnant face down, and place a weight on it. Let dry.

2. Measure from the floor to the center of the doorknob. Subtract 1 inch. Measure this length up from the bottom of the board and mark with a pencil. Using a 2-inch hole saw drill attachment, drill through board and carpet, with the top of the hole meeting the line you have marked. Note: Make sure the hole is big enough for your doorknob; 2 inches works for most.

3. Add 3/4-inch-wide lattice strip trim to all four edges, using wood glue and finish nails. The lattice can be painted to match the door, if desired.

4. Optional: Attach the bottom of the cat scratcher to the bottom of the door with heavy-duty Velcro, to keep the scratcher from swinging. Cats can be enticed to use the board with a little catnip until they get into the habit.
