Why Cat Flaps Are Essential For Maine Coons & Which Are The Best!
Maine Coons are majestic, adventurous, and enormous cats. Males typically weigh 18-22 pounds, and females weigh 15-18 pounds.
Given their curiosity and size, a standard cat flap is often too small and restrictive for them.
Installing a properly sized cat flap gives them:
- Freedom to explore outdoors safely
- Prevents behavioral stress from scratching or whining at the door
- Supports your cat’s physical and mental health
Why Cat Flaps Are Beneficial
1. Freedom Of Movement Encourages Healthier Habits
Maine Coons are an active, adventurous breed that thrives on having access to both indoor and outdoor spaces.
Installing a cat flap allows them to come and go as they please, which means they’re able to get more natural exercise throughout the day without relying on you to open the door every time they want to go out.
This helps prevent boredom and promotes a healthier lifestyle, particularly for cats prone to weight gain or those living in smaller homes without much vertical climbing space.
2. Reduced Stress And Behavioral Issues
Many behavioral issues in cats, such as clawing at furniture, vocalizing excessively, or aggressive play, are rooted in boredom or frustration.
A cat flap provides an outlet for your Maine Coon’s energy and curiosity. When they have the autonomy to explore, patrol their territory, or bask in the sun, they tend to be more relaxed and content.
This also helps reduce stress-related behaviors, especially in cats that dislike feeling confined.
3. Independence Suits Their Temperament
Maine Coons are friendly and social cats, but they also enjoy their independence. Unlike some clingy breeds, Maine Coons often appreciate time to themselves outdoors or in a quiet spot away from household hustle and bustle.
A cat flap lets them control their environment, choosing when to go outside or return home, without needing human assistance.
This fosters their natural sense of independence and reduces anxiety during busy family routines.
4. Convenience For Owners
From a practical standpoint, a cat flap is a major convenience!
You won’t need to constantly open the door, especially in the middle of the night or early in the morning, just because your cat wants to go out.
Maine Coons are large, and if they’re pushing or pawing at the door frequently, it can be disruptive.
A well-installed flap eliminates this constant back-and-forth, making life easier for you and more peaceful for the household.
5. Supports Maine Coon Size And Strength
When you choose a properly sized cat flap, one designed for pets up to 25 pounds, you’re giving your Maine Coon a stress-free way to enter and exit without squeezing or stooping.
A cat of this size, with a broad chest and long tail, needs more room than the average feline.
A large, smooth-swinging flap allows for comfortable, dignified use. It also supports their muscular build by encouraging daily movement between indoors and outdoors.
6. Safe And Secure Outdoor Access
High-quality modern cat flaps often include microchip technology, timers, or 4-way locking systems, which give you greater control over your Maine Coon’s comings and goings.
These features help keep unwanted animals, like neighboring cats or wildlife, from entering your home.
For households in busy neighborhoods, rural areas, or near other pets, this is a vital security measure. It ensures that only your cat has access, and only at times you choose.
7. Easier Integration With Outdoor Cat Enclosures
If your Maine Coon has access to a catio (enclosed outdoor play area) or a fenced garden with cat-proof barriers, a cat flap is the perfect way to let them enjoy that space safely without leaving a door open.
It bridges the indoor-outdoor divide while maintaining a secure boundary.
This setup is especially useful for owners who want to give their cats fresh air and freedom while minimizing risks like traffic, predators, or theft.
Top-Rated Cat Flaps And Doors
Here are the top-rated extra-large cat flaps on Amazon that comfortably accommodate a full-grown Maine Coon (males 18-22 lb, females 15-18 lb). Each option is explained with real pros and cons to help you choose.
PetSafe Big Cat Door 2.0
This upgraded version of the classic Big Cat Door (available on Amazon) features a spacious 7 1/4″ × 7 3/4″ opening, a weight capacity up to 25 lb, and a soft-close flap with a secure 4-way lock. It’s designed to fit both interior and exterior doors.

SureFlap Microchip Pet Door Connect
The SureFlap Microchip Pet Door Connect (available on Amazon) is a Wi-Fi-enabled smart pet door that works with your cat’s existing microchip (or SureFlap RFID collar tag).
Designed for larger cats and small dogs, its internal dimensions and build quality make it suitable for Maine Coons weighing up to 22 lb.
It connects to the Sure Petcare Hub (sold separately) and a free mobile app, giving you remote control and monitoring of your pet’s comings and goings—anywhere in the world.
Pros:
- Generous Flap Size: The flap opening measures approximately 7” × 6.7” (178 mm × 170 mm) which is large enough for most adult Maine Coons.
- Selective Entry/Exit: Recognizes up to 32 pet microchips or RFID tags. You control who enters and when, which prevents intrusions from strays or raccoons.

Cons:
- Hub Sold Separately: To use the smart features, you must buy the Sure Petcare Hub, adding to the cost.
- Premium Price Tag: More expensive than standard microchip flaps or mechanical models.
- Not Ideal for XXL Maine Coons: While it fits most Maine Coons, those with exceptionally broad shoulders or long torso length may find it snug. Always measure your cat’s width and height before purchase.
- Battery Reliance: Loses smart function when batteries die, though there’s a low-battery warning to help you plan.
Choosing The Ideal Cat Flap: Step-By-Step
Here’s how to select the best cat flap for your beloved feline friend:
1. Opening Size And Load Capacity
To ensure your Maine Coon can pass through comfortably:
- Measure the widest part of the cat (usually shoulders or chest).
- Measure from the top of the shoulders to the belly.
- Add 1-2 inches to both measurements to allow for a comfortable, stress-free passage, taking into account their fluffy coat.
A mature male Maine Coon often needs a flap opening of at least 7″ × 7″, while females may manage with just slightly smaller (but still generous) dimensions.
Ensure both width and height include extra room for their chest and shoulder girth.
2. Material And Flap Motion
Soft, spring-mounted flaps are easier for cats to push and provide better insulation. Heavy, rigid flaps may discourage use.
3. Locking Options
Four-way locks (in/out/all/locked) give full control. Microchip-enabled flaps restrict access to your pets only.
4. Weatherproofing
Look for flaps with magnetic seals, brush strips, or dual-layer insulation. This keeps your home comfortable and saves energy.
5. Installation Compatibility
Check thickness adaptability for doors, glass, or walls. Telescoping frames work well across different setups.
6. Durability And Replacement Parts
Choose models with ABS or polycarbonate frames, and ensure flap replacement parts are available.
Cat Flap Vs. Pet Door – Which Is Better?
Both options allow pet access, but their design and benefits differ:
- Cat flap: Compact, easy to install, and ideal for interior or door use. Generally less expensive, though basic models may compromise weather resistance.
- Pet door: Larger, sturdier, and better insulated – especially suitable for exterior doors or frequent outdoor access. Larger flap protects against drafts and uneven terrain, but are bulkier and costlier.
If your Maine Coon has access to a yard, or you live in a colder climate, a pet door may be more suitable.
For indoor use or milder climates, a high-quality cat flap is usually sufficient.
