The best door solution depends on what you mean by “keep cats out.” If you need a barrier that blocks a cat while letting air and light through, a reinforced zippered screen is the closest fit. If you want a door held partly open for a cat but closed off to a larger pet, an adjustable latch may work better. Below, we compare five options and explain where each one makes sense—and where it may not.

Our Picks: Best Door To Keep Cats Out Of Room reviews
1. QWR Reinforced Cat Screen Door: A Stronger Mesh Barrier
The QWR is a removable mesh barrier for an interior doorway. Its thickened, vinyl-coated steel-wire mesh is intended to stand up better to claws than ordinary fiberglass screen, and its double zipper gives you a way to pass through without removing the whole screen. It can also help separate cats while they see and smell one another.
The screen measures 34 by 82 inches and is listed for door openings up to 32 by 80 inches; the door frame is not included in that opening measurement. It attaches with hook-and-loop strips, with nails suggested for firmer installation on wooden frames. Some users report that it is straightforward to install and that the mesh and zippers feel sturdy in everyday use. Clean the mounting surface first, and confirm the frame gives the strips a secure place to hold.
This is the best match here if your goal is to block a cat from crossing a doorway without closing off airflow. Still, it is a fabric screen rather than a rigid door: a persistent climber or a poorly secured edge may challenge the barrier, so check it regularly.
Pros:
- Reinforced mesh is designed to resist scratching and climbing better than standard screen material.
- Double zipper provides access through the barrier.
- Allows air to move between rooms.
- Can help separate cats while allowing them to see and smell each other.
Cons:
- Requires careful measuring of both the opening and available frame area.
- Adhesive mounting may need extra support on some frames.
Verdict: Choose the QWR if you want a cat-focused screen barrier with reinforced mesh and a zippered opening.
2. Door Buddy Door Prop: An Adjustable Gap for Cat Access
The Door Buddy is a latch-and-strike-plate system that holds an interior door ajar. Its opening adjusts from 3 to 5.5 inches, so a cat can pass through while a larger dog may be kept out. That makes it useful for access to a litter box or another room where you want the cat to go in freely.
Its purpose is different from a screen door: it does not keep a cat out of the room. Instead, it keeps the door from closing fully and controls the size of the gap. Installation involves replacing the existing strike plate with the included one, using the existing screws. The product includes a Torx tool for adjusting the opening. Because the gap is designed around the size of your pets, measure carefully and consider whether your cat can pass through it.
This option may suit renters or anyone who wants a removable solution without cutting a cat door into the door itself. It is less useful when you need a room fully off-limits to your cat, and it depends on a suitable latch and strike-plate setup.
Pros:
- Adjustable opening lets you set a gap for cat access.
- Uses existing strike-plate screw holes rather than adhesive or new cuts.
- Can be removed and reused.
- Door can be opened from either side and pushed back into the propped position.
Cons:
- Designed to let cats in, not keep them out.
- The adjustable gap may not suit every pet size or door setup.
Verdict: Pick the Door Buddy when your goal is to give a cat access while restricting a larger pet, not when you need to exclude the cat.
3. BFNN Cat Screen Door: A Tall, Removable Mesh Gate
The BFNN is another zippered mesh option for keeping cats out of a room while preserving airflow and visibility. The maker describes its PVC mesh as more wear-resistant than standard plastic mesh, and the widened hook-and-loop strips are intended to help secure it to the frame. Double zippers make it possible to open the screen from either side.
The screen itself measures 34.3 by 83.5 inches and is listed for door openings up to 32 by 80 inches. The product also specifies a frame requirement of 34.3 inches, so check the measurements and mounting area before ordering rather than relying only on the opening width. It attaches with hook-and-loop strips and can be removed without drilling.
Compared with the QWR, the BFNN also offers a removable zippered mesh barrier, but the listed materials and fit details differ. It may work well where you want visibility and ventilation, though any fabric screen depends on secure attachment and should be checked for gaps or loosening.
Pros:
- Designed to block access while maintaining airflow and visibility.
- Double zippers make it easier to pass through from either side.
- Hook-and-loop mounting does not require drilling.
- Removable for doorways where a permanent gate is not wanted.
Cons:
- Its stated frame requirement makes measuring especially important.
- Mesh may not be suitable for a cat that forcefully climbs or pushes at barriers.
Verdict: Consider the BFNN if its frame and opening measurements fit your doorway and you want a removable screen with visibility through it.
4. Mdavo Magnetic Screen Door: Convenient Passage, Not Cat Exclusion
The Mdavo is a hands-free mesh curtain with magnets along the center seam. The panels part when someone walks through and are meant to close behind them. It is listed as 38 by 82 inches and fits doors up to that size, not including the frame. Hook-and-loop tape is used for installation, and the screen can be removed and stored.
This is a useful choice for letting people and pets move through a doorway while allowing fresh air in and helping keep insects out. But because the screen opens easily and is intended for pets to pass through, it is not a reliable way to keep a cat out of a room. Some users report that the magnets close neatly and that careful surface cleaning helps the adhesive strips hold.
Compared with the QWR and BFNN, the Mdavo favors easy, hands-free passage over pet separation. Choose it for airflow and convenience, not as a cat-proof gate.
Pros:
- Magnetic center seam is designed to close after passage.
- Allows airflow through the doorway.
- Does not require tools for the stated hook-and-loop installation.
- Removable and foldable for storage.
Cons:
- Not designed to stop a cat from entering or leaving.
- Adhesive performance can depend on a clean, suitable mounting surface.
Verdict: Choose the Mdavo for easy passage and ventilation, but look at a reinforced zippered screen if you need to keep a cat out.
5. NestGuard Child Proof Door Lock: A Strap to Limit Door Opening
The NestGuard is an adhesive-mounted strap lock intended to limit how far a door opens. The strap is adjustable, and the product is described as suitable for several door types, including sliding, pocket, bifold, and double doors. It requires no drilling, but the instructions say not to apply it to drywall or wallpaper.
For cat owners, its potential use is controlling access by limiting the door gap. However, the product is not a dedicated cat barrier, and its description also mentions creating a gap for pets to pass through. Whether it keeps your cat out depends on the opening you set and your cat’s size and behavior. Some users report using the adjustable strap on a screen door, but that does not establish a fit for every doorway.
Compared with the mesh options, the NestGuard does not cover the doorway or maintain a full visual barrier. It may be worth considering when you need a simple way to restrict a door’s swing, but it is not the clearest choice for reliably blocking a cat from a room.
Pros:
- Adjustable strap lets you control how far the door opens.
- Adhesive installation does not require drilling.
- Listed for several door styles.
- Can be removed, though adhesive suitability depends on the surface.
Cons:
- Not specifically designed as a cat-exclusion barrier.
- Should not be installed on drywall or wallpaper, according to the product details.
Verdict: Consider the NestGuard only if limiting the door opening is enough for your situation and the resulting gap will keep your cat on the desired side.
How to Choose a Door Solution to Keep Cats Out
Start with the direction of access
Check whether you need to keep your cat out of a room, keep another pet out while the cat goes in, or simply make it easier to walk through a doorway. These are different jobs. A zippered screen is the most direct fit for blocking a cat while keeping the doorway open to air. The Door Buddy is designed for the opposite arrangement: it leaves a gap for a cat while restricting a larger dog.
Measure both the opening and the mounting area
Measure the clear door opening before choosing a screen. Then check the frame area where hook-and-loop strips will attach. The QWR is listed for openings up to 32 by 80 inches, while the BFNN lists a 34.3-inch screen width and also calls for 34.3 inches of frame space. The Mdavo is larger and is listed for door sizes up to 38 by 82 inches. Compare your measurements with the specific product details, not just the product title.
Consider your cat’s behavior
A screen may be a practical barrier for a cat that respects it, but it is still flexible mesh. If your cat climbs, scratches hard, pushes at edges, or squeezes through small gaps, pay close attention to the attachment and inspect it often. A latch or strap only limits a door’s opening; it does not provide a full-height barrier.
Choose the right level of airflow and visibility
Mesh screens let air and light pass through while creating a visible boundary. That can be helpful when you want to separate pets without shutting off the room completely. A standard magnetic curtain focuses more on easy passage and bug control, so it may not provide the separation you need. A solid closed door offers a different kind of boundary but does not provide the same airflow through the doorway.
Check installation and surface compatibility
Hook-and-loop screens need a clean, suitable surface to attach to. Some products suggest added nails for wooden frames, so consider whether that is acceptable in your home. The Door Buddy replaces the strike plate using existing screws, while the NestGuard uses an adhesive strap and should not be mounted on drywall or wallpaper according to its product information.
Think through daily use
If people need to pass through often, look at how the barrier opens and closes. The QWR and BFNN use zippers, which require a person to open and close the screen. The Mdavo uses a magnetic seam for hands-free passage, but it is not designed to keep a cat out. Pick the design that matches both your access needs and your cat’s ability to defeat it.
Frequently Asked Questions
What is the best type of door barrier for keeping a cat out of a room?
A reinforced zippered screen is the most direct option among these products because it covers the doorway while allowing airflow. The QWR and BFNN are both designed as cat screens. Fit and secure attachment matter, and a determined cat may still test a mesh barrier.
Will a magnetic screen door keep my cat out?
Not reliably. The Mdavo is designed to part when people or pets pass through and close behind them. It is better suited to airflow and insect control than to restricting a cat’s access.
Does the Door Buddy keep cats out of a room?
No. It holds a door partly open so a cat can enter while a larger dog may be kept out. It is useful for managing access in that direction, not for excluding a cat.
How do I measure for a cat screen door?
Measure the clear opening’s width and height, then check how much flat frame space is available for the mounting strips. Compare both measurements with the product’s stated opening and screen dimensions. Do not assume the size in the title includes the door frame.
Can I use a child safety strap to keep a cat out?
Possibly, if the strap lets you set a door gap your cat cannot pass through. The NestGuard is not specifically designed as a cat barrier, so check the gap in practice and make sure the adhesive is suitable for your door surface.
Are zippered screens suitable for introducing cats?
They can help create a visual and scent barrier while keeping cats physically separated. The QWR description specifically presents this as a possible use. Supervise introductions and make sure the screen is securely attached.
Should I choose the QWR or BFNN screen?
Compare your doorway measurements and the listed frame requirements first. The QWR describes reinforced, vinyl-coated steel-wire mesh; the BFNN describes PVC mesh and widened hook-and-loop strips. Either may suit a doorway that matches its fit requirements, but neither replaces checking the mounting and barrier regularly.
Final Recommendation
For keeping a cat out while maintaining airflow, start with a reinforced zippered screen such as the QWR, provided its opening and mounting dimensions fit your doorway. The BFNN is another screen-style option to compare against your frame measurements. Choose the Door Buddy when you want a cat to pass through while keeping a larger dog out, and the Mdavo when easy passage matters more than containing a cat. The NestGuard may help limit a door’s opening, but it is not a dedicated cat barrier.
