Kitty Door




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

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.

    Good job of it. Seems unfortunate to ruin a good solid wood door. I think I'd find a cheap hollow core door. One could also use vinyl weather stripping to edge the inside cut.

    Thank you. Said door is a hollow core. I was considering something like vinyl weather stripping, but I find that I'm more interested in the next project.

    Let's take a moment to talk about shop safety:

    Nice. This kind of opening will also help with the air circulation in your room.
