If you need a replacement flap for any dog or cat door, locking cover, or other pet door parts, it’s crucial that you choose the right kind. Most parts are not interchangeable between brands or models from the same manufacturer even if the dimensions seem to match. Be sure to check the door’s dimensions before ordering a replacement flap. If, for some reason, you order the wrong type of flap, simply contact Zen Pet Supplies, mail back the incorrect order, and we’ll send you the correct replacement flap.

There are differences between a double and single replacement flap for your cat door. Typically, a single flap pet door has one flap on the inside of the house while a double flap has two flaps, one on the inside and one of the outside of the house. Single flaps are less expensive, and depending on the climate, may be your best bet. Double flaps insulate better and are recommended for colder areas of the country. Also, double flaps can be more difficult to train your pet to use compared to single flaps because some less-than-bold cats may be reluctant to push harder to get through the door. You may be wondering how to determine what size cat door to get for your pet. Here’s the answer to your question: The best way to measure your pet is from the bottom of his feet to the tallest part of his back; this will give you an idea of the height the flap needs to be. You can open a door in your home wide enough for your pet to walk through comfortably with a little room on either side and measure that opening.
