Best Screen Doors With Pet Flaps for Dogs and Cats
The best screen door with a pet flap depends on your pet’s size and the closure features you need. PetSafe’s large model is suited to pets up to 100 pounds, while its small model is designed for pets up to 30 pounds. Namsan offers a magnetic flap with side locks, and Ownpets is sized for small animals. Billionchains is another magnetic auto-close option. Compare the flap opening—not just the suggested pet weight—before choosing.
| Product | Best For | Listed Size or Feature |
|---|---|---|
| PetSafe Large | Larger pets | 10.2 x 17-inch opening; up to 100 lb |
| Namsan | Pets needing a lockable flap | 12 x 14-inch inside opening |
| Ownpets | Small dogs and cats | 8 x 10.2-inch opening |
| PetSafe Small | Pets up to 30 lb | Snap-in DIY installation |
| Billionchains | Magnetic auto-close access | Magnet and dual locking tabs |
PetSafe Large Screen Door
Best for: Larger dogs or households that need a generous flap opening. PetSafe lists this model for pets up to 100 pounds, with an opening measuring 10.2 inches wide by 17 inches high.
The door works with most metal or vinyl-coated fiber screens and is described as compatible with storm doors, windows, and porches. Its stated size and screen compatibility make it a useful option to compare when a small cat flap would be too restrictive.
Keep in mind: The 100-pound figure is not a substitute for measuring your pet. Check shoulder width and height against the opening before purchase.
Namsan Magnetic Lockable Screen Door
Best for: Owners who want a magnetic flap and a way to restrict pet access. Namsan lists an inside opening of 12 by 14 inches. Built-in magnets help the flap close after a pet passes through, and two blue side locks can be used to prevent passage.
The frame is made of ABS material, and the included screws and nuts secure the frame. The product description also says the flap can be replaced, which may be useful if that component needs attention later.
Keep in mind: Confirm the opening dimensions against your pet and check that the frame can be secured to your screen-door setup.
Ownpets Magnetic Cat Screen Door
Best for: Cats, small dogs, and other small animals. The listed flap opening is 8 inches wide by 10.2 inches high, making this a more compact choice than the large PetSafe model or Namsan door.
Its magnetic flap is designed to close automatically after a pet exits, and the door is described as lockable. The listing says it is suitable for screen doors, so it may suit buyers looking for a small flap without a larger opening.
Keep in mind: The compact opening is intended for small pets. Avoid choosing it based on the product name alone; measure your pet to ensure comfortable passage.
PetSafe Small Screen Door
Best for: Cats and smaller dogs up to 30 pounds, according to the product listing. This option is designed to snap into an existing screen door, window, or porch screen for DIY installation.
The high-impact plastic frame surrounds mesh described as puncture- and tear-resistant. That construction may appeal to buyers seeking a framed flap rather than a simple opening in the screen. The product description notes that the large door is reinforced with fastening screws; do not assume that detail applies to this small model.
Keep in mind: The listed pet limit is 30 pounds, so larger animals should be matched to a suitable opening and model.
Billionchains Magnetic Auto-Close Pet Door
Best for: Buyers prioritizing magnetic closure and access control. The listing describes a magnet at the bottom that pulls the flap back into position, plus dual locking tabs to restrict passage.
Installation uses screws and instructions, with the frame attached to the screen area before cutting the screen along the frame. The maker recommends having two people perform the installation. For pets new to screen flaps, the listing advises guiding them through with treats until they adapt.
Keep in mind: The supplied product details do not state a flap opening size or pet weight limit. Check those measurements before deciding whether it fits your animal.
Buying Guide: How to Choose a Screen Door With a Pet Flap
How do you choose the right flap size?
Measure your pet’s height and width at the points needed to pass through the opening, then compare those measurements with the product’s listed flap dimensions. A weight limit alone does not confirm that the opening will be comfortable. Among these options, Ownpets lists an 8-by-10.2-inch opening, PetSafe Large lists 10.2 by 17 inches, and Namsan lists a 12-by-14-inch inside opening.
Do you need a magnetic flap or a lock?
Magnetic closures are intended to help return the flap to a closed position after use. Namsan and Ownpets describe magnetic closure and locking features; Billionchains lists magnetic auto-close and dual locking tabs. If controlling when your pet can pass matters, verify how the specific locking mechanism works before purchase.
Will the door fit your screen?
Check the product’s stated screen compatibility and installation method. PetSafe Large specifies most metal or vinyl-coated fiber screens and mentions storm doors, windows, and porches. PetSafe Small describes a snap-in installation. Namsan and Billionchains use screws, so consider whether you can attach a framed flap and cut the screen as directed.
What matters most for daily use?
Consider your pet’s size, whether you want to lock the flap, and how much installation work you can manage. A smaller opening suits smaller animals, while a larger opening may be necessary for bigger pets. Introduce the flap gradually if your pet is unfamiliar with this type of access.
