Installation Instructions

Ideal Cat Flap Installation Instructions

Ideal Cat Flap Installation



  • Straight edge/ruler

  • Drill

  • Drill bits

  • Keyhole/scroll saw

  • Phillips screwdriver

Letters inside the ( ) correlate to the images above.



Step 1: Determine the pet door height. The distance between the bottom of the door and bottom of template should be 6”. Center the template (width) in the middle of the door and tape in place.

Step 2: With the template in place (A), draw around the edge of the template onto the door. Mark the corner holes with a nail or awl.

Step 3: Using the corner locations as your guide, drill four individual holes with a drill no longer than ½â€.

Step 4: Starting on the inside of one of the drilled holes (B), cut just inside of the line using a keyhole or scroll saw.

Step 5: Insert the inner frame that contains the flap (C) into the opening from the interior side. Make sure that the frame is flush with the door surface. Caulking is recommended under the outer frame. Place the outer frame that does not contain the flap (D) into the opening from outside the door. Hold it in place and install the screws. Do not overtighten.


For Doors with Uneven Surfaces

After cutting the rough opening, build up the lowest areas with a wood frame thick enough to create an even door surface. Then proceed with the steps above.

For Walls:

Once the wall opening has been made, it is necessary to build a frame to cover the exposed area between the wall surfaces. When cutting through walls, use extreme caution and make sure not to cut any concealed wires, gas lines, or water pipes.

For Steel Doors:

Use a jigsaw with a hacksaw blade to cut the opening, starting at the pre-drilled corner holes. Then proceed with the steps above.


Installation of the Ideal Larger Cat Door, the "Chubby Kat'


Can I lock the flaps?

Yes, both doors have a 4-way lock. So you can set it for open, completely locked, in only, or out only.

Does the door keep out the weather?

It does do pretty well, but this is more of a three-season mild climate use.

Is this pretty durable?

It is really one of the most durable, economic cat doors for doors.

How do I know which flap size?

The best way would be to cut a hole in cardboard to the 6.25" x 6.25" flap size and see if they can get through. If not, then go with the large flap or Chubby Cat Doors version.

What is the flap made of?

The petsafe 4-way locking cat flap is a rigid clear polycarbonate.

Is the frame plastic or metal?

It is plastic.

Are there different colors?

The door is only in white, but you can paint the plastic framing.

Can I use it in doors less than 1 1/4" thick?

You can. You would just have to use shims or foam weatherstripping to build on the back of the pet door frames.

Is there a wall version?

You could use the door on a wall, but the contractor would have to frame it out as there is not a tunnel available.

Is the large the same size as the Ideal Hefty Kat Door?

They are the exact same door (also known as the Chubby Cat Door) that works well for big cats.

What keeps air from blowing in around the flap?

There is a fuzzy pile weatherstripping around the door flap’s flap opening which helps keep it sealed and keep out cold air.

Can you get a cover for the door?

No, there is no Ideal replacement locking cover for the door as it has the four-way security locking feature.

Is the large flap cut out the same as the Chubby Cat?

They are actually the same door. The Chubby Cat was also known as the Ideal Hefty Kat, then was changed to the Large Cat flap.
