Ideal 4-Way Locking Cat Doors


Both use unbreakable clear polycarbonate (others use Plexiglas). The opening is larger than usual--especially the Hefty Cat size.

The bright white frames telescope to allow for a self-framing fit between 1 1/4" and 1 3/4 " which covers standard interior and exterior doors.

This Cat Flap and Hefty Cat Flap incorporate a 4-way locking mechanism. And it's also available in a patio panel version at Ideal Patio Cat Door.

The large cat flap is identical to the ideal chubby cat door, or the hefty cat door in dimensions, they just updated the name.

Note that Ideal Pet Products are also marketed as "Perfect Pet Products". The Ideal Cat Door is used in the Ideal Cat Panel for sliding glass doors and in the Ideal Cat Sash. However, the manufacturer trims the frame in the process. If you need to replace the cat flap portion in one of these units, be sure to tell us and we'll make special arrangements to have your unit trimmed. Sorry, but we cannot do this with sale priced units.

  • Good economy cat door review by Jack
    5 4 Good economy cat door

    I like that the large version of this cat door is large 7.5 wide by 10.5 tall. It allows plenty of room for my Maine Coon cat. See through flap and neat locking system (locked, unlocked, in only or out only) is a bonus.

  • Works well for the price review by Sam
    5 4 Works well for the price

    Had one of these on the back door to my condo for years (I was renting and it was installed before I moved in). The magnet didn't seal the flap super well so occasionally we would get some decent wind driven rain that would come in when it stormed. It was tile so we just put down a towel and it was fine. I was surprised how well the flap actually held up with all the constant use and I would get one of these again if I needed another cat door.

  • Just what I needed review by Iris
    5 4 Just what I needed

    The 4-way locking mechanism is just what I was looking for for my cats who need to stay inside during the night (because of coyotes and other wild animals). A lot of the electronic models were quite pricey and I didn't mind changing the lock settings every day, so this was a great, inexpensive solution. Love it so far!

  • Decent, but not the best review by Paula
    5 3 Decent, but not the best

    I install this on the door to my backyard. It worked great for a few years but not the knobs to lock it are not doing its job. My cat also gained a bit of weight over the years so the cat flap is a bit snug.

  • Let door review by Glenda
    5 5 Let door

    The home we bought, had this in it, but it was scratched up, the only place I could find this one was here, Thanks for having it!!!

  • great concept - needs improvement review by Suzette
    5 3 great concept - needs improvement

    We thought that we had found the perfect door to deal with one indoor cat (at night) and one outdoor cat. Unfortunately, besides the lock becoming looser and looser, the door has an edge all around it and both my cats have figured out how to grab it with a claw, pull it inwards and and let themselves out when the door is set on "in-no out". Not a problem for the outdoor cat, but definitely an issue for the one we keep in at night. We had to put epoxy all around the door to remove the edge. - until the cats find the next trick... Otherwise, it's a great concept and easy to install.

  • POOR QUALITY review by TESSA

    Your website states that you care and create quality
    I beg to differ
    In three years this cat flap;
    Insulation gone
    Door latch too loose doesn’t latch
    Lexan door too strong for frame so pivot point is worn down making the door not fit properly
    For the price this should be a very long wearing useful cat flap
    False advertising is against the law
    You should be ashamed to produce something so faulty

  • Door is Manufactured with excellent material - Excellent sales staff review by SAM
    5 5 Door is Manufactured with excellent material - Excellent sales staff

    My previous door that was installed in the window sash unit needed to be replaced because children kept going through opening and caused it to function improperly. At first I had a difficult time ordering the door only without the complete window unit. I could not locate the replacement on the web site and called the sales team and found the staff very helpful. They gave me the correct part number and called to make sure I received the correct item. . The door assembly works better than I anticipated and I am very pleased with sales force.

  • Good door, bad locking mechanism review by K-dub
    5 4 Good door, bad locking mechanism

    The door works great and easy install with the right tools. My 2 cats love to be able to go in and out on their own now. The locking mechanism is not too great though. I've seen them "pop" the lock by just pushing on the door firmly. And when they do this they end up locking themselves outside. I just leave it open all the time now. Good door if you aren't interested in it locking. Maybe my cats are just stronger/more determined than others...

  • Great product but short lifespan review by Natco747
    5 4 Great product but short lifespan

    This is my third Large Cat 4-way locking cat door. Whule I love the product and it works for both of my two large cats and small dog, the locking mechanism fails after about 24 months. I use the locking toggle every day and sometimes several times a day. Eventually it becomes sloppy will not stay in firmly in position. The door can then be pulled or pushed to allow the cats to get out. Since the locking device is in the frame, the entire door must be replaced...which I continue to do. Otherwise it is a great door.

  • good product review by sooz
    5 4 good product

    good sturdy product and good price. I have had the same one before and I would like the 4 way lock to have a larger easier handle since it is so awkwardly near the floor.

  • It works review by Bill w
    5 4 It works

    It's bigger than the last one I had. Cats fit through it better. When it's closed it has a pretty good seal. It doesn't like to close to that point on its own very often. Usually leaves a 1/2 inch gap. They love it. They can sit inside and look out. It's big. They tear in and out where they used to squeeze through the old one. He's thin and she's fat. She fits fine now. He brings in birds and rabbits and wood peckers and mice and etc...

  • Locking cat door. review by Mia
    5 5 Locking cat door.

    I purchased this item. I am very happy with it, and my cat loves being able to come in and out easily without bothering me to open the door for her. It took her 3 days to learn how to use the pet door, and now she is comfortable with it. I like to be able to lock it, or have it only work for her to go out, OR to come in as well. It is a great item and well worth the price I paid for it.

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

Ideal Cat Flap Installation Instructions

Ideal Cat Flap Installation

Tools required for installation:

Straight edge/ruler . Drill . 1/2 Drill Bits . Key Hole or Scroll Saw . Phillips Screwdriver

Simple 6-Step Installation

Letters in ( ) correlate to diagram above:

    • Step #1:

      Determine pet door height. The distance between bottom of door and bottom of template should be 6". Center template (width) in middle of door and tape in place.
    • Step #2:

      With template in place (A), draw around edge of template onto door. Mark corner holes with a nail or awl.
    • Step #3:

      Using corner locations as your guide, drill four individual holes, using a drill no larger than 1/2".
    • 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 inner frame (C) (with flap) into the opening from interior side (inside and outside frames have been clearly marked for easier assembly). Make certain frame is flush with door surface. Caulking is recommended under outer frame. Place outer frame (D)(no flap) into opening from outside door, hold in place, then install screws and tighten until snug. Do not over-tighten.
    • Step #6:

      To use the Four-Way Lock, see instructions on Cat Flap frame.

Uneven surfaced doors:

      After cutting the rough opening, build up the lowest areas with wood frame thick enough to create an even door surface. The Cat Flap can be installed in walls, steel doors, and storm doors. Note that additional materials, such as wood framing, plaster, touch-up paint, longer frame screws, and extra tools may be required.


      Once wall opening has been made, it will be necessary to build a frame to cover the exposed area between wall surfaces. Use wood screws to attach interior and exterior frame to wall surfaces. When cutting through walls, extreme caution must be used to not cut any concealed electrical wires, gas lines, or water pipes.

Steel doors:

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

Click below to expand:

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

It does do pretty well, but we would say this is more 3 season mild climate use.

It is really one of the most durable economical cat doors.

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.

It is a rigid clear polycarbonate.

It is plastic.

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

You can, you would just have to use shims or a foam weather stripping to build up on the back of the pet door frames.

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

They are actually the exact same door (also know as the Chubby cat door).

There is a fuzzy pile weather stripping around the flap with helps keep it sealed.

No there is no ideal replacement locking cover for the door as it has the four way locking feature.

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.
