Step 1: Box selection
- best boxes/storage bins have flat sides (easier to cut doors out)
- screw down the lid to the box with six nuts and bolts (this is so the kennel does not come apart)
-screw locations should be spread out to offer most strength (the corners and in the middle of the long sides are ideal spots)
- cut the entrance opening with a hack saw (start bending it downwards at the corners to make it cut downwards, this creates a nice rounded corner.
- drill ventilation holes around the top of the box (I used a 1" drill bit, spacing isn't critical as long as it's fairly even)
