Petsafe Cat Flaps

In need of a simple interior cat door installation? The PetSafe Indoor Cat Flap is designed to fit solid core wood doors commonly found in interior homes. The thin flap provides cats with comfortable use and easy adjustment. This cost effective cat door comes with the option of a two-way or four-way locking device, depending on your needs. The two-way lock can either be completely locked or unlocked, and the four-way lock can be set to in only, out only, as well as completely locked or unlocked. Not only do inside cat flaps minimize litter odor from reaching unwanted areas of the house, they are great for preventing dogs or kids from getting into the litter box or accessing cat food!

  • for the money an excellent product review by Nancy
    5 5 for the money an excellent product

    It was easy to install with the proper tools although it took some time. The cats adjusted almost instantly as I put food on the other side to encourage them to go through. It has only been a week so I haven't let the flap down yet, assuming they will figure it out?.

  • Decent door review by Lex
    5 4 Decent door

    Perfect to prevent the dogs from getting into the litter pan. It's too small for them but kitten can squeeze through ok. Works perfect for what we needed.

  • Good for Indoor Use review by Mars
    5 3 Good for Indoor Use

    Good pet door for the cost. Small opening so good for cats or very small dogs. I like the 4-Way lock so I can set it for fully open, locked, in-only or out-only. Helps control the cat's movement.

  • Great value for its price review by Kim
    5 5 Great value for its price

    I am using this for my 3 cat's litter box and this is an awesome and affordable solution! My cats were able to learn how to use this pretty easily and we are able to keep the litter box smell contained. I can see why this is for indoor use only because the flap has almost zero resistance.

  • Good for indoor use review by Jackson
    5 5 Good for indoor use

    Used it in the door going from the family room to the laundry room where the cat's litter box is. Not very well insulated, so would just use indoors as instructed. Great value for the price and product works as described.

  • Does what it should review by Kitties4ever
    5 3 Does what it should

    Obviously not the most expense highest rated out there, but works well for letting them into the closet to get to the litter box. I don't think I would have this going outdoor to their cat palace though, when they say indoor they mean indoor. Good overall for how cheap it was.

Petsafe Indoor Cat Flap Instructions

  • Step 1: Determine the location of the pet door you are going to install on the door by drawing a 7 ¼” horizontal line on the door equal to the height of your cat at the shoulders.
  • Tip: Make sure that the center of the line is also directly in the center of the spot you want to install the pet door. Use a level to make sure that the line is accurate.
  • Step 2: Now draw a vertical 7 ¼” line that goes directly through the center mark of your first line (should look like this +). Again, use a level to make sure that it is straight and accurate.
  • Step 3: Take off the door by removing the hinge pins.
  • Tip: This makes cutting the hole much easier, but if you are unable to remove the pins proceed to step 5.
  • Step 4: Put the door on a raised level surface, like a work bench or saw horses.
  • Tip: Make sure that you use clamps to secure the door so that it doesn’t move.
  • Step 5: Place the template included on top of the lines drawn matching them up and trace around the template.
  • Tip: Tape the template down to hole it in place with painters tape.
  • Step 6: Once the line is drawn remove the template. Use the level to make sure all lines are accurate.
  • Step 7: Next you will need to drill ½” diameter holes in the 4 corners of the line you traced for the cut out. These will serve as pilot holes helping you to make a more straight and even cut.
  • Step 8: Now cut out the opening for the pet door using a jigsaw. Making sure that the blade used is correct for the material your door is made of.
  • Tip: In order to protect the door finish you can use masking tape as a liner on the outside of the cut out line so that the saw doesn’t damage the visible part of the people door.
  • Step 9: Now do a quick check to make sure that the cat door inside frame into the opening. Then do the same with the outside frame.
  • Step 10: Once the fit is checked center the inside frame into the cut out and mark the screw holes with a pencil then remove the frame.
  • Step 11: Next you will need to drill holes for the screws. If your door is wood the holes should be 5/64” and if your door is metal 7/64”.
  • Step 12:. Place the inside frame back on the door and use a screwdriver to attach it.
  • Step 13: Take the outside frame and peel back one side of the double sided tape and stick it to the back of the frame.
  • Step 14: Last remove the other liner from the tape and stick the outside frame onto the door, and push to secure it in place.

That is the door with a lock that will allow you to either lock the door completely or leave it open so the pet can go in and out.

This has a 4-way locking mechanism so you can not only have it closed or open, but in only or out only.

It will come stock in white, but you can paint it.

It is more economy style, but cats tend to be more gentle and since it should be for inside use only it should hold up well.

Make hole 5 3/4" x 5 3/4" in a piece cardboard and see if they can get through.

Yes you can use it on thin materials.

Something similar would be the Ideal 4-way Locking Cat Door or the Cat Mate 221 Cat Door.

It is meant to be fairly simple, but it does require using a jigsaw so you do have to be handy.

Yes, but they are only available through PetSafe directly.

Not this one, but there are other doors that are similar made by Cat-Mate like the Cat Mate 221 Cat Door that have a larger flap.

For purposes of this limited warranty, “PetSafe Certified Refurbished Products” means buy-back products, returned products, pre-owned products, and/or scratch & dent products that PetSafe has:

  • Fully tested 
  • Refurbished by replacing any defective modules identified during testing

PetSafe warrants that each PetSafe Certified Refurbished Product will be free from defects in material or workmanship for a period of ninety (90) calendar days from the original date of purchase. During the warranty period, PetSafe will, at its option, replace with new or refurbished products or parts, any products or parts determined to be defective. In the event of a product defect, these are your only remedies. This warranty gives you specific legal rights and you may also have other rights, which vary from state to state.

This limited warranty covers only product issues caused by defects in materials or workmanship during ordinary consumer use and does not cover product issues caused by any other reason, including, but not limited to, product issues arising out of or related to commercial use, acts of God, misuse, limitations of technology, or customer modification of any part of the PetSafe Certified Refurbished Product.

All express and implied warranties, including without limitation any implied warranties of merchantability and fitness for a particular purpose, are limited in time to the term of this limited warranty. No warranties, whether express or implied will apply after the expiration of the limited warranty period.

Except as provided in this warranty and to the extent permitted by law, PetSafe is not responsible for direct, special, incidental or consequential damages resulting from any breach of warranty or condition, or under any other legal theory. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above exclusion or limitation may not apply to you.
