This instructable illustrates how to make your own interactive puzzle for your cat.
I call it the KittyLand Puzzle Center
Step 1: Materials
Fabric: old T-shirts work well, you'll need enough for approx. 1700sq inches. Cut out into approx 4in x 4in squares. You will need 108.
Corrugated plastic board (24in x 18in)
108 Magnets (the stronger and thinner the better)
Ruler, marker, scissors, exacto-knife, sewing machine, hot glue gun, something small and round
Step 2: Getting Square
Draw circles of various sizes onto the squares and carefully cutout using scissors or an exacto-knife. You can leave some without circles to act as a bottom to your cube.
Insert magnets into opposite corners of the plastic square by wedging them into the corrugated portion of the plastic squares. Make sure the magnets have opposite poles out; i.e., one positive, one negative. Hot glue the washers onto the open corners.
Step 3: Assembling The Sides
Once you have completely sewn the perimeter of the insert, carefully sew around the hole.
