Cat Flap in a Baby Gate

Step 3 Cut a Hole in the Bars

Anchor your gate door to your work surface with clamps, and measure out the space you want to open up for your cat flap. I measured across 3 bars (four spaces) to get 10 inches. So I wanted a 10x10 square hole when I Was done, about 9 inches off the ground (the rise of one step, so the cat could get through the gate - if I put the hole at ground level, the first step would block the hole).

I marked the cuts with pencil on the bars, and used the dremel saw with a metal jigsaw bit to cut the bars out.

Save the bars for future projects, or at least keep one nearby to verify the size of the holes you'll drill in the one-by.
