Introduction: 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.
Step 1: Materials Needed
- Safety goggles (let's take a moment to talk about shop safety)
- Tape measure
- Plate (or other 6 inchish object)
- Jig saw
Step 2: Measure Your Cat
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.
Step 3: Remove the Door
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.
Step 4: Find the Center
Measure the width of the door, and make a mark in the center.
Step 5: Find the Apex
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.
Step 6: Find the Width
Mark the width of the cat door with two more lines.
Step 7: Draw the Arch
I found a paper bowl that was pretty close to six inches, so I used that to draw my arch.
Step 8: Cut Out the Door
Wearing your safety glasses? Good. Using your jigsaw, cut an arch.
Step 9: Hang the Door
Put the door back on and replace those hinge pins.
Kitty knows right where to go, and the dogs can no longer get in.
