Single Flap or Double Flap? Double flaps would provide more insulation for your home, perfect for climates that experience extreme hot or cold weather. This page is the double flap version, but if you live in a more temperate climate, single flaps would be enough.

Note: Endura Flap pet doors are not recommended for use by kittens or very small dogs. Cats have been successful using the Small #06; however, a few have found the Medium #08 difficult to use. We would not recommend using the Large #10 or Extra Large #12 or any of the double flap versions for cats.

There has been lots of discussion as to why the Endura Flap is such a high-performing pet door, but for engineers or those looking for some more technical information here is a 74-page dog door energy efficiency study showing what makes it so special.
