Description: I followed the basic instructions but skipped the part about the drawers instead opting to use one of the side panels from a drawer to join the two drawer fronts together. Once attached using the 2 provided L bracket that were supplied + 1 other larger one I had bought at Ikea as well I mounted the drawer fronts to the unit.
With all parts together I put the back on but only nailed the top part down to the middle then used a jig saw to trim off the bottom half, then jigged out the cat door oh so very carefully.
The entry hole is protected around the edges with Ikea cable tube held on with the remaining nails from the backing. The bottom where the box is sitting on is one of the drawer bottoms.
Last steps were to add in a motion sensitive light and I added 2 more L brackets with another drawer side to act as a brace so the box won’t shift when in use. The concern was the cat could potentially trap himself in side.
