Best Smart Pet Doors for Keeping Raccoons Out: SureFlap vs. PetSafe SmartDoor vs. Pawport

Compare SureFlap, PetSafe SmartDoor, and Pawport to find the best smart pet door for blocking raccoons and allowing safe pet access.

Best Smart Pet Doors for Keeping Raccoons Out: SureFlap vs. PetSafe SmartDoor vs. Pawport

If your cat or dog needs outdoor access but raccoons, stray animals, or other wildlife keep approaching the pet door, a basic flap is the wrong tool. The key question is not simply which door is “smartest.” It is which access method, locking system, size, installation format, and backup behavior fit your home and your pet.

A raccoon may be able to push through or manipulate a weak plastic flap. The Internet Center for Wildlife Damage Management also notes that any opening usable by a pet may be usable by a wild animal, especially when the door or surrounding installation is vulnerable. (ICWDM) Washington Department of Fish and Wildlife recommends reducing attractants such as food near the door and using an electronically activated opener linked to the pet when an opening must remain available.

For most households, the best starting point is a pet-specific identification system rather than a door that stays unlocked. Among the products compared here, SureFlap is the strongest fit for microchipped cats and small dogs, PetSafe SmartDoor is the more flexible collar-key option for medium and large pets, and Pawport is the most interesting retrofit choice for owners who already have a pet-door opening and want a sturdier smart barrier.

What matters most when blocking raccoons

1. Identification must be reliable

A door that recognizes an individual pet is less dependent on a manual lock schedule. Microchip recognition is convenient if your pet is already chipped and the chip is compatible. Collar keys and tags can work well, but the collar must remain attached, functional, and comfortable for the animal.

For cats that dislike collars, a microchip-based door is usually the cleaner approach. For large dogs, collar-based systems may be more practical because product size and identification options are often different between cat and dog models.

2. Entry and exit are not the same

This distinction is especially important in multi-pet homes. Suppose one cat is allowed outside while another must remain indoors. A system with selective entry but unrestricted exit may let the indoor-only cat leave.

The SureFlap DualScan is designed around individualized entry and exit permissions and can store up to 32 pet identities. (Sure Petcare) By contrast, the SureFlap Microchip Pet Door Connect uses selective entry, but its exterior reader allows any animal to exit. (Sure Petcare) That makes the Connect attractive for keeping raccoons out while allowing approved pets to come inside, but it is not equivalent to fully selective entry and exit.

3. Physical security still matters

Electronic authorization is only one layer. The frame, flap, bolts, surrounding door, and installation opening also need to resist pushing, prying, and gaps. A larger opening may be necessary for a large dog, but it also creates a larger potential route for wildlife if the locking system is defeated.

No smart pet door should be treated as an absolute wildlife-proof guarantee. In areas with persistent raccoon activity, combine the door with a nighttime lock schedule, secure installation, and removal of food, water, trash, and other attractants from the immediate area.

SureFlap DualScan: best for microchipped cats and multi-pet control

The SureFlap DualScan Microchip Cat Door is the clearest choice when your priority is controlling which cats may enter and leave. It reads an existing pet microchip or a SureFlap RFID collar tag, supports up to 32 registered identities, and allows individualized entry and exit permissions. (Sure Petcare) SureFlap also specifically markets the model as a way to prevent intruder animals, including raccoons. (Sure Petcare)

This model has a 5 5/8-by-4 3/4-inch flap opening and is designed for cats. It can be installed in a door, wall, or glass panel with the appropriate accessories. The product uses four AA batteries, with stated battery life of up to 12 months. (Sure Petcare)

Choose it if:

Your cats are microchipped or can wear RFID tags.
One or more pets need to stay indoors.
You want selective exit as well as selective entry.
You do not need the Connect model’s app-based notifications and remote controls.

Watch-outs: The opening is intended for cats, not large dogs. Check the actual flap dimensions and your cat’s body size before ordering. Glass, wall, and unusual door installations may also require additional parts or professional work.

SureFlap Microchip Pet Door Connect: best app-enabled option for large cats and small dogs

The SureFlap Microchip Pet Door Connect expands the opening to 7.5 by 6 11/16 inches and is designed for large cats and small dogs. It recognizes an existing microchip or Sure Petcare RFID collar tag. (Sure Petcare)

Its connected features include remote locking and unlocking, curfew scheduling, entry and exit notifications, and activity monitoring. The separately sold Sure Petcare Hub is required for app connectivity. (Sure Petcare)

The Connect’s most important limitation for wildlife-conscious multi-pet households is its access direction: it provides selective entry, but any animal can exit because the reader is on the exterior side only. (Sure Petcare) If your main concern is stopping raccoons from entering, that may be acceptable. If you need to keep a specific indoor-only cat from leaving, choose a system with selective exit control instead.

Choose it if:

You want microchip access plus app control.
Your pet is a large cat or small dog.
Remote locking, curfews, and notifications are valuable.
Your household does not require selective exit for individual pets.

Watch-outs: Budget for the Hub, batteries, and any wall, window, or glass installation accessories. Battery life is stated at up to six months using four C-cell batteries. (Sure Petcare)

PetSafe SmartDoor Connected: best for collar-key access and larger pets

PetSafe’s SmartDoor Connected Pet Door uses a collar-mounted Pet Door Key. The Medium model can also pair with implanted microchips, while the Large model is intended to use collar keys. (PetSafe) It is available in Medium and Large sizes, making it a more natural candidate than the cat-focused SureFlap models for households with bigger dogs.

The SmartDoor supports selective entry and exit, individualized schedules, remote lock and unlock control, activity notifications, and lock notifications. It also uses a multi-point locking mechanism and dynamic weather sealing. (PetSafe) Those features address both wildlife control and day-to-day convenience, although actual security still depends on correct installation and the pet door’s surrounding structure.

The system requires a 2.4 GHz-capable Wi-Fi connection for connected functions. It can run on batteries or an optionally sold wall adaptor. (PetSafe)

Choose it if:

Your dog is too large for a cat-door format.
Your pet reliably wears a collar tag.
You need selective exit for a multi-pet home.
You want schedules and notifications without relying on a microchip in the Large model.

Watch-outs: Confirm whether the Medium or Large opening fits your pet—not just the exterior frame. Door and wall installations may require tunnel or installation adaptors, and the optional wall adaptor adds to the total system cost.

Pawport: best retrofit choice for an existing pet-door opening

Pawport takes a different approach. Its Smart Pet Door is marketed as a retrofit product that mounts over virtually any existing pet door without professional installation. Pawport also offers complete systems for new or remodel installations. (Pawport)

The hardware uses steel and aircraft-grade aluminum construction, dual steel deadbolts, a weatherproof seal, anti-pinch operation, app control, pet tracking, and smart-home integration. The pet wears a waterproof Smart Pet Tag. (Pawport) Pawport lists Medium, Large, and Extra Large configurations; for new installations, its published recommended pet weights are up to 100, 150, and 200 pounds, respectively. (Pawport)

The official site lists the Smart Pet Door at $699, while its Designer Series is listed from $699 and Signature Series from $849. Prices and configurations can change, so verify the current product page before purchasing. Optional components include tunnel and frame systems, an outdoor pet door, a glass mount, rechargeable battery options, and additional power accessories. (Pawport)

Choose it if:

You already have a pet-door opening and want a retrofit-oriented solution.
You have a large dog and want a larger configuration.
Physical construction, deadbolts, and smart-home integration are priorities.
You are prepared to confirm how the Smart Pet Tag controls access in your intended setup.

Watch-outs: A retrofit installation is different from installing a new opening in a wall, door, or glass panel. New or remodel projects may require Pawport’s tunnel and frame components or other installation work. Also include tags, power options, frames, and mounts when comparing total cost.

Which smart pet door should you buy?

Best for microchipped cats with indoor/outdoor rules: SureFlap DualScan.
Best for app control with a large cat or small dog: SureFlap Microchip Pet Door Connect, provided unrestricted exit is acceptable.
Best for larger dogs and selective entry and exit: PetSafe SmartDoor Connected, especially when a collar key is practical.
Best for retrofitting an existing opening or prioritizing robust hardware: Pawport.

Before ordering, measure your pet’s shoulder width, chest depth, and height, then compare those measurements with the actual flap opening. Confirm microchip compatibility or collar-tag fit, Wi-Fi requirements, battery or power behavior, replacement-part availability, and whether your installation needs a tunnel, frame, adaptor, or professional help.

Finally, use the door’s lock schedule strategically. Locking it during the hours when raccoons are most active, keeping food and water away from the opening, and checking for gaps around the installation can be just as important as choosing a connected product. The goal is layered wildlife exclusion—not simply a door with an app.
