Kitty Door

I recently moved, and had to find a new home for the litter box, the bathroom. I also have two dogs, and they had taken to snacking when I wasn't paying attention. Hence, the kitty door. It needs to be big enough for the cats, but not big enough for the dogs.

• Safety goggles (let's take a moment to talk about shop safety)
• Tape measure
• Pencil
• Plate (or other 6 inchish object)
• Jig saw
• Square
• Screwdriver
• Hammer

Measure from your cat's belly to their shoulder, and your cat's width too.

I wanted a little extra room, but I measured one of the dogs to see how much room I had. I decided to make the door 7 inches high, and 6 inches wide.

If you remove the hinge pins, the door comes right off. I was able to remove both pins with a screwdriver and a hammer. Hang onto those pins. You'll need them to put the door back on.

Measure the width of the door, and make a mark in the center.

Measure from the bottom of the door up about 7 inches, and make a mark. Hopefully, this mark intersects with the one you made previously. If you need to, redo the previous step to get the marks to intersect.

Mark the width of the cat door with two more lines.

I found a paper bowl that was pretty close to six inches, so I used that to draw my arch.

Wearing your safety glasses? Good. Using your jigsaw, cut an arch.

Put the door back on and replace those hinge pins.

Kitty knows right where to go, and the dogs can no longer get in.
