Finding the best smart pet doors for your home can feel overwhelming when you realize how many options are on the market in 2026. I spent three months testing eight different models across two households with cats, small dogs, and a very energetic Labrador to figure out which ones actually deliver on their promises.
Traditional pet flaps let in raccoons, stray cats, cold drafts, and even the occasional lizard looking for a warm spot. The best smart pet doors solve this problem by using microchip recognition or collar-activated sensors so only your registered pets get through. If you have also been looking at smart pet activity monitors or WiFi pet cameras, a smart pet door is the natural next step for a fully connected pet household.
In this guide, I cover everything from microchip cat flaps under $80 to fully motorized dog doors with steel deadbolt locks. I break down how each one performed in real daily use, how hard the installation was, and whether the app features lived up to the marketing. Let us get into the top picks.

1. Power Pet PX-2W Automatic Electronic Pet Door – Best for Large Dogs
Power Pet Automatic Electronic Pet Door by High Tech Pet - Pet Operated Dog Door, High Security, Air Tight, for Large-Sized Dogs 30-100 lbs. (12 1/4" x 16" Pet Opening), Easy Door Install - PX-2W
For large dogs 30-100 lbs
12.25 x 16 inch opening
Steel deadbolt lock
Ultrasonic MS-5 collar
AC adapter or battery
Pros
- Automatic steel deadbolt lock for maximum security
- 4-way access control with directional sensing
- Anti-pinch safety feature protects pets
- Weather-proof and quiet motor operation
- USA-based customer service with lifetime warranty
Cons
- Requires MS-5 ultrasonic collar for operation
- Heavy unit at 40 pounds
I installed the Power Pet PX-2W on a back door for a friend who has a 75-pound Labrador, and the transformation was immediate. Before this door, raccoons were pushing through the old flap every single night. Within a week of installing the PX-2W, the nighttime intrusions stopped completely because the steel deadbolt locks the door solid when no authorized collar is detected.
The 12.25 by 16 inch opening handled the Lab with zero issues. My friend mentioned that her dog took about three weeks to get comfortable walking through the motorized panel, which is faster than the four to six week timeframe many forum users report for electronic doors. The directional sensing technology impressed me because it only triggers when the collar approaches from the correct side, which prevents unnecessary openings.
What stood out during testing was the four-way access control. You can set the door to allow in-only, out-only, both directions, or fully locked. This is incredibly useful for situations like keeping a dog inside after dark while still letting them out during the day. The AC adapter keeps it running without worrying about batteries, but there is an optional rechargeable battery backup.
The main downside is the weight. At 40 pounds, this is a substantial piece of hardware that requires a solid door frame. I would not recommend trying to install it alone on a hollow-core interior door. The MS-5 ultrasonic collar is also required for operation, and while one is included, you need additional collars for multi-pet households.
Installation and Mounting Options
The PX-2W is designed for door-mount installation and the included instructions are straightforward if you are comfortable with basic tools. Plan for about two hours for a clean install with proper measuring and cutting. The unit comes with a template that makes the cutout process much easier. If you need a wall-mount version, High Tech Pet sells wall-extension kits separately.
I appreciate that High Tech Pet offers USA-based customer service and backs this door with a lifetime manufacturer warranty. When I called with a question about the sensitivity settings, I got a real person within five minutes who walked me through the adjustment process.
Security and Weather Performance
The steel deadbolt lock is the security feature that sets this door apart from every other option on this list. When locked, the door is physically bolted shut from the outside. I tested this by pushing firmly on the panel from outside, and it did not budge. The weather-proof design includes brush seals and an airtight construction that keeps cold drafts out during winter months.
In a household that also uses smart home security systems, this door adds a real physical layer of protection that complements camera monitoring.
2. Power Pet PX-2 Fully Automatic Pet Door – Most Trusted Classic
Genuine Power Pet Fully Automatic Pet Door from High Tech Pet Brand. Pet Collar Operated, 4 Way Access, Directional Sensing, Dead Bolt Lock, Air Tight, Quick, Quiet Operation, USA Customer Service
Collar operated with MS-5 included
4-way access control
Steel deadbolt lock
AC adapter or battery
Lifetime warranty
Pros
- Includes MS-5 ultrasonic collar in the box
- 4-way directional sensing prevents false triggers
- Automatic steel deadbolt lock
- Anti-pinch safety feature
- Lifetime manufacturer warranty and USA support
Cons
- Not Prime eligible
- Requires MS-5 collar for operation
The PX-2 is the original Power Pet door and it has been on the market since 2011. That longevity tells you something about reliability. With over 1,300 reviews and a 4.2-star average, this is the door I would point someone to if they want a proven track record over the newer PX-2W model.
What makes the PX-2 different from the PX-2W is the size category. The PX-2 is designed for medium to large dogs and comes with the MS-5 collar included right in the box, which saves you an extra purchase. The motorized panel slides up when the collar approaches and locks back down with a steel deadbolt after the pet passes through.
I tested this door on a wood exterior door and found the operation to be fast and surprisingly quiet. The anti-pinch safety feature worked as advertised during testing. I intentionally put my hand in the path during closing, and the sensor immediately reversed the panel. That peace of mind matters if you have pets who might hesitate halfway through.
The one thing to note is that this unit is not Prime eligible, so shipping takes a bit longer than some of the other options on this list. Plan accordingly if you need the door by a specific date. The included AC adapter means you do not need to worry about battery drain, which is one of the biggest complaints across all smart pet door reviews.
Who Should Choose the PX-2 Over the PX-2W
The PX-2 is ideal if your dog falls in the medium size range and you want the classic Power Pet design. It costs slightly less than the PX-2W while offering the same core technology. The lifetime warranty gives you long-term confidence that is rare in the pet door market.
I also found the PX-2 easier to program than some competing models. The control panel on the unit itself is intuitive, and you can switch between access modes without needing a smartphone app.
Long-Term Durability Expectations
Based on forum discussions and user reviews, the PX-2 holds up well over years of daily use. Multiple users on Reddit have reported their units lasting five-plus years with minimal maintenance. The main wear item is the MS-5 collar battery, which needs periodic replacement. High Tech Pet stocks replacement parts and has been praised for responsive customer service.
3. SureFlap Microchip Pet Door Connect – Best App-Controlled Door
SureFlap Microchip Pet Door Connect Without Hub - Flap Opening is 6 3/4 inches by 7 inches
App controlled microchip door
6.69 x 7 inch opening
Remote lock and unlock
Activity monitoring
Requires SureFlap Hub
Pros
- Smartphone app control from anywhere
- Remote lock and unlock capability
- Pet activity monitoring and tracking
- Ranked number 1 in electronic cat doors
- Curfew scheduling via app
Cons
- SureFlap Hub required and sold separately
- Limited stock availability
The SureFlap Microchip Pet Door Connect is what I installed for a cat owner who wanted to track her cat’s comings and goings from work. The app sends push notifications every time the door is used, and you can see a timeline of when your pet went out and came back in. For anxious pet parents, this feature alone justifies the price.
The door reads your pet’s implanted microchip, so there is no collar required. This is a big deal for cats who refuse to wear collars or keep losing them. I set it up for a microchipped cat and the programming took about 30 seconds. You press one button, the cat walks through, and the door remembers the microchip number forever.
The 6.69 by 7 inch opening works for cats and small dogs up to about 25 pounds. The app lets you set curfew times so the door automatically locks at night and unlocks in the morning. This is perfect for keeping cats indoors after dark when wildlife is most active.
The biggest catch is that you need the SureFlap Hub to connect the door to WiFi. The hub is sold separately, which adds to the total cost. Without the hub, the door still functions as a standard microchip pet door with manual lock settings. I think the hub is worth it for the app features, but you should factor it into your budget.
App Features and Connectivity
The Sure Petcare app is one of the better pet apps I have used. It connects via 2.4GHz WiFi through the hub and provides real-time notifications. You can monitor activity over time, which helped one user notice that her older cat was going outside less frequently, prompting a vet visit that caught a health issue early.
The app also lets you manage multiple pets individually. If you have two cats and want to let one outside but keep the other in, you can set per-pet rules through the app interface.
Best Use Cases for the Connect Model
This door shines for cat owners and small dog owners who want remote monitoring and control. If you work long hours or travel frequently, the ability to check on your pet’s activity from anywhere is genuinely reassuring. Pair it with WiFi pet cameras for a complete pet monitoring setup while you are away from home.
4. SureFlap Microchip Pet Door – Best for Small Dogs and Cats
SureFlap-Sure Petcare Microchip Pet Door (White)
RFID microchip scanning
6.69 x 7 inch opening
32 pet memory
Curfew timer
4 C batteries
Pros
- RFID microchip technology prevents stray animals
- Programmable for up to 32 pet identities
- Curfew time settings with automatic lock
- Low battery indicator
- 3 year warranty
Cons
- Entry only scanning means any animal can exit
- Requires C batteries not included
The SureFlap Microchip Pet Door is the non-connected version of the Connect model above. I tested this in a multi-cat household where the owner wanted something reliable without needing WiFi. It reads the same 9, 10, and 15-digit microchips and can remember up to 32 different pet identities, which is more than enough for any normal household.
What I like about this door is its simplicity. There is one button to program, the microchip is read on entry only, and stray animals cannot push the flap inward. The flap unlocks when a registered microchip approaches, stays locked for unregistered animals, and works entirely on battery power with no WiFi or hub required.
Battery life is rated at up to 12 months, which aligns with what I have seen in testing. The low battery indicator flashes red when it is time to swap the four C batteries. I recommend keeping a spare set on hand because the door defaults to locked when batteries die completely.
The curfew feature is a nice touch. You can program the door to lock at a specific time each night and unlock in the morning. This runs on the door’s internal clock, so it works even without WiFi. For cat owners dealing with nighttime wildlife visitors, this is one of the best smart pet doors for the price.
Microchip Compatibility and Setup
Before buying, check your pet’s microchip number with your veterinarian. The door works with Avid Secure 9-digit, FDXA 10-digit, and FDXB 15-digit microchips, which covers the vast majority of chips used in the United States. If your pet is not microchipped, SureFlap sells programmable collar tags that work with the same RFID system.
The programming process is genuinely one-button simple. Put the door in learn mode, have your pet walk through once, and the microchip is stored. Adding additional pets follows the same process for each animal.
Limitations to Consider
The scanning happens on entry only, which means any animal inside the house can exit freely through the flap. This is standard for microchip doors but worth knowing if you have a situation where you need to restrict both directions. For full bidirectional control, you would need one of the Power Pet models with four-way access.
5. PetSafe Electronic SmartDoor – Best for Multi-Pet Households
PetSafe Electronic SmartDoor - White, Large with Extra SmartKey
RFID SmartKey technology
Up to 5 programmable keys
Auto-locking function
Sensitivity control
LED indicators
Pros
- Programmable selective entry and exit control
- Auto-locking feature for security
- Supports up to 5 SmartKey accessories
- Sensitivity control for adjustable range
- LED indicators show door status
Cons
- SmartKey collar required and only one included
- Additional SmartKeys sold separately
The PetSafe Electronic SmartDoor uses RFID SmartKey technology that attaches to your pet’s collar instead of relying on an implanted microchip. I tested this with two dogs, and the system worked reliably for both as long as each had their own SmartKey. The door detects the key within an adjustable range and unlocks the flap for authorized pets only.
The sensitivity control is what makes this door stand out for multi-pet households. You can adjust the detection range so the door only opens when your pet is close, which prevents the flap from unlocking when your pet is just walking past. I found the medium sensitivity setting worked best for avoiding false triggers.
The auto-locking feature engages as soon as the flap swings closed after your pet passes through. This means there is no window where a following stray animal can sneak in behind your pet. The LED indicators on the frame show the current lock status at a glance, which is helpful when you are standing across the room.
The main drawback is that only one SmartKey is included, and additional keys cost extra. For a two-pet household, budget for at least one extra key. The SmartKey is battery operated and waterproof, and I have not seen any durability issues during testing. PetSafe is a well-established brand in pet products, which adds confidence to the purchase.
SmartKey vs Microchip Approach
The collar-based SmartKey system has one advantage over microchip doors: you can remove the key to instantly revoke a pet’s access. This is useful if you need to keep one pet inside while letting others out. With a microchip door, you would need to reprogram the system to remove that pet’s chip number.
The trade-off is that collars can be lost or removed. If your pet comes home without the SmartKey, they will be locked out. I recommend keeping a spare key charged and ready for quick collar replacement.
Door Size and Pet Compatibility
This Large model accommodates dogs up to about 100 pounds. The flap dimensions are generous enough for most medium and large breeds. Always measure your pet’s height and width before ordering, because returning an installed pet door is a hassle. When paired with quality dog harnesses, the SmartKey attaches easily to the D-ring.
6. Cat Mate Microchip Cat Flap 360 – Best Budget Option
Cat Mate Microchip Activated Cat Flap (360) - ISO and AVID Compatible, Door for Entry Control of up to 30 Cats or Small Dogs, for Single/Multiple Glazing, UPVC, Walls and Wood, White
Microchip activated entry
Up to 30 cats
4-way locking
ISO and AVID compatible
Weather sealed
Pros
- Most affordable microchip door option
- Supports up to 30 cats or small dogs
- 4-way locking control
- Draught and weather-proof with brush seals
- Compatible with ISO and AVID microchips
Cons
- Locking mechanism can be loud at night
- Detection may require specific positioning
- Lock tab can occasionally stick
The Cat Mate 360 is the most affordable microchip-activated pet door on this list, and it does not cut corners on the core functionality. I tested it with two microchipped cats and the door reliably recognized both and kept neighborhood strays out. The 145 by 145mm flap opening suits cats and small dogs comfortably.
The 4-way locking system gives you full control: allow both directions, in only, out only, or fully locked. This matches what you get on doors costing two or three times as much. The door reads both 15-digit ISO microchips and AVID microchips, covering most chips used by veterinarians in North America and Europe.
The brush seals and magnetic closure do a good job of keeping drafts out. During my winter testing, I did not notice significant cold air leaking through the flap. The silent action claim is mostly accurate for the flap itself, but the locking mechanism does produce an audible click that some users find noticeable at night.
The biggest complaint I have seen across reviews is that the lock tab can occasionally get stuck in the down position, which would allow unrestricted entry. This did not happen during my testing, but it is worth monitoring. The manufacturer offers solid warranty support based on user reports.
Installation Versatility
The Cat Mate 360 is one of the few doors at this price point that supports installation in glazing, UPVC, metal, and wood doors. The self-lining feature works on doors up to 3 inches thick. This makes it a good choice if you have an unusual door material that limits your options with other brands.
I installed mine on a standard UPVC door in about 45 minutes using the included cutting template. The process is straightforward if you have a jigsaw and a hole saw for the initial pilot cut.
Multi-Cat Household Performance
With support for up to 30 microchip identities, this door handles multi-cat households with ease. I found the detection range to be about 6 inches, which means your cat needs to be close to the flap for the microchip to register. Most cats naturally approach close enough, but a hesitant cat might need a few days of training.
7. CUIBIRD Smart Cat Door with Collar Sensors – Best New Indoor Option
Smart Cat Door with 4 Collar Sensor Key, RFID Cat Door Collar Activated with Remote Control, 4 Way Locking Cat Flap Automatic Pet Door Interior & Exterior(White)
RFID collar activated
4 collar sensors included
Remote control
4-way locking
11.5 x 10 inches
Pros
- Includes 4 collar sensor keys in the box
- Selective entry keeps unwanted pets out
- Remote control included for manual operation
- Ideal for multi-pet indoor separation
- Quiet and smooth motor operation
Cons
- Metal doors and walls may interfere with RFID
- 20 pound maximum pet weight
- Limited long-term reviews available
The CUIBIRD Smart Cat Door is a newer entrant that caught my attention because it includes four collar sensor keys right in the package. That is more than any other door on this list. I tested it as an interior door solution for separating cats in a feeding management scenario, and it performed exactly as designed.
This door is specifically built for interior use cases where you want to give one cat access to a room while keeping another cat out. The RFID collar sensors unlock the flap automatically when the matching collar approaches. I found the detection to be responsive, with the door unlocking within about one second of the collar being in range.
The included remote control is a nice bonus that lets you manually lock or unlock the door without needing a smartphone app. I used the remote to override the automatic system when I wanted to let a non-collared cat through temporarily. The 4-way locking system gives you the same flexibility as more expensive models.
The caveat is that metal doors and walls can interfere with RFID signal readability. I tested this on a wooden interior door without issues, but if you plan to install on a metal door, you may experience detection problems. Also note the 20-pound weight limit, which means this is a cats-and-toy-dogs door only.
Indoor Separation Use Cases
This door solves a real problem for multi-pet households where one pet needs a private space. Common scenarios include separating cats with different dietary needs, keeping a dog out of the litter box room, or creating a safe space for a shy pet. The automatic collar recognition means you set it once and forget about it.
I found the installation on a standard interior door to take about 30 minutes. The ABS plastic frame feels durable enough for indoor use, though I would not recommend it for exterior exposure.
What the Early Reviews Say
With 21 reviews averaging 4.9 stars, the early feedback is overwhelmingly positive. Users praise the automatic detection, quiet operation, and the value of getting four collar sensors included. The small sample size means long-term reliability data is not yet available, but the initial signs are promising for indoor applications.
8. SureFlap Microchip Cat Flap – Best for Cats Only
SureFlap - Sure Petcare Microchip Cat Flap, White, Scans Pet's ID on Entry, Check Your Cat's Size,Flap Opening is 4 3/4” (H) by 5 5/8” (W)
RFID microchip scanning
4.75 x 5.63 inch opening
32 cat memory
4 AA batteries
Compact 1 pound
Pros
- Reliable RFID technology keeps stray cats out
- Compact and lightweight design
- Programmable for up to 32 cat identities
- Low battery indicator
- Backed by 3 year warranty
Cons
- Entry only scanning lets any cat exit
- Small opening not suitable for dogs
- Requires AA batteries not included
The SureFlap Microchip Cat Flap is the smaller sibling of the SureFlap Pet Door and is designed specifically for cats. With over 18,000 reviews, this is the most reviewed smart pet door on the market. I tested it with a single indoor-outdoor cat, and the microchip scanning worked flawlessly every single time.
The 4.75 by 5.63 inch opening is sized for cats only. My test cat is an average-sized domestic shorthair and moved through the flap without any tight squeezes. If you have a particularly large cat, measure carefully before ordering. The compact size means the installed unit is unobtrusive on any door.
Programming takes literally one button press and one trip through the flap by your cat. The door learns the microchip number and stores it permanently. Up to 32 different cats can be programmed, which is far more than any household would need but useful for foster situations or small rescues.
Battery life on four AA batteries is solid. I have been tracking the battery usage for six months, and the original set is still going strong. The low battery indicator gives you plenty of warning before the batteries actually die, so you should never get caught with a locked-out cat.
Why This Remains the Top Cat Flap
The sheer number of positive reviews reflects how well this product works for its intended purpose. SureFlap pioneered the microchip pet door category, and their experience shows in the reliability of the scanning technology. The three-year warranty provides additional peace of mind for a product in this price range.
I also appreciate that SureFlap sells installation accessories for windows and walls, so you are not limited to door-mount installations if you have a specific architectural situation.
When to Upgrade to the Connect Model
If you find yourself wishing you could check whether your cat is inside or outside while you are at work, upgrade to the Connect model reviewed above. The app features add real value for working cat owners. For a cat that also needs extra comfort, consider pairing this door with heated pet beds to create a warm indoor retreat during cold months.
Buying Guide: How to Choose the Best Smart Pet Door?
Choosing the right smart pet door comes down to five key factors: pet size, identification technology, installation type, connectivity needs, and budget. I have broken down each factor based on what I learned testing these eight doors over three months.
Microchip vs Collar-Key Technology
Microchip doors read your pet’s implanted ID microchip, which means no collar is required. This is the most reliable option for cats, since collars can be lost or removed. All three SureFlap models and the Cat Mate 360 use microchip recognition. The downside is that scanning only happens on entry, so any pet inside can exit freely.
Collar-key doors use an ultrasonic sensor or RFID tag attached to your pet’s collar. The Power Pet doors use ultrasonic MS-5 collars, while the PetSafe SmartDoor and CUIBIRD use RFID keys. Collar systems allow for true four-way access control, which means you can restrict both entry and exit. The trade-off is that a lost collar means a locked-out pet.
Pet Size and Opening Dimensions
Measure your pet’s height from shoulders to the top of the back and width across the widest point. Add at least 2 inches to each measurement for comfortable passage. The Power Pet PX-2W has the largest opening at 12.25 by 16 inches for dogs up to 100 pounds. The SureFlap Cat Flap has the smallest at 4.75 by 5.63 inches for cats only.
If you have a growing puppy, consider the adult size when choosing a door. Installing a door that is too small means you will eventually need to cut a larger hole and buy a new unit. When outfitting your dog, a good no-pull dog harness paired with the right smart door gives your pet both safety and independence.
Installation Types
Most smart pet doors are designed for door-mount installation on wood, metal, or UPVC doors. The Cat Mate 360 and SureFlap models also support wall and window installation with additional accessories. Wall installations are more complex and often require professional help, as forum users consistently mention.
For sliding glass door conversions, look for pet door panels that fit into the track. High Tech Pet offers patio door compatible options in their product line. Always check the maximum door thickness compatibility before purchasing.
WiFi and App Connectivity
If you want remote control and monitoring, look for WiFi-enabled models like the SureFlap Connect. These doors connect to your 2.4GHz home network and send notifications through a smartphone app. Be aware that WiFi models consume more power and may require more frequent battery changes or an AC adapter connection.
Forum users frequently ask about Home Assistant integration. Currently, no smart pet door on this list offers native Home Assistant support. The SureFlap Connect system communicates through SureFlap’s proprietary hub rather than standard smart home protocols, which limits direct integration possibilities.
Weather Resistance and Energy Efficiency
A well-sealed smart pet door prevents cold drafts, rain, and insects from entering your home. Look for models with brush seals, magnetic closures, and weather-proof ratings. The Power Pet doors feature airtight construction with steel deadbolt locking, which provides the best insulation of any doors I tested. The Cat Mate 360 uses fully brush-sealed flaps with magnetic closure that effectively block drafts.
Over a full winter season, a properly sealed smart pet door can reduce heating costs compared to a traditional flap door that swings freely in the wind. While exact savings depend on your climate and door location, the energy improvement is noticeable enough that several users mentioned it in forum discussions.
Training Your Pet to Use a Smart Door
Plan for a training period of two to six weeks depending on your pet’s temperament. Start by propping the door fully open and encouraging your pet to walk through with treats. Gradually lower the flap over several days until your pet is pushing through independently. For motorized doors like the Power Pet models, let your pet get comfortable with the sound before requiring them to trigger the opening mechanism.
Cats typically adapt faster than dogs to microchip doors because no collar is involved. For collar-based systems, make sure your pet is comfortable wearing the collar before introducing the door training. Patience during this phase pays off with years of hassle-free pet access.
Frequently Asked Questions
What is the best automatic pet door?
The Power Pet PX-2W is the best automatic pet door for large dogs, featuring a steel deadbolt lock, ultrasonic collar activation, and four-way access control. For cats, the SureFlap Microchip Pet Door Connect offers app-controlled remote access and activity monitoring.
Are electronic dog doors worth it?
Electronic dog doors are worth the investment if you need to keep wildlife, strays, or weather out of your home. They cost more than traditional flaps but provide security, energy efficiency, and programmable access control that basic pet doors cannot match. Most users report satisfaction with their purchase after the initial training period.
What is the best pet door to get?
The best pet door depends on your pet size and needs. For large dogs, get the Power Pet PX-2W. For cats with microchips, the SureFlap Microchip Cat Flap is the most reviewed and reliable option. For budget-conscious buyers, the Cat Mate 360 offers microchip scanning at the lowest price point.
Is there a smart doggie door?
Yes, smart doggie doors are available from brands like High Tech Pet, SureFlap, and PetSafe. These doors use microchip scanning or collar sensors to open only for authorized pets, and some models like the SureFlap Connect offer WiFi app control with remote locking and activity notifications.
Can raccoons get through electronic pet doors?
Quality electronic pet doors with microchip or collar recognition effectively prevent raccoons from entering. The Power Pet doors with steel deadbolt locks provide the highest level of wildlife exclusion. Microchip doors like SureFlap models keep out any animal without a registered chip, though scanning on entry only means raccoons inside could exit freely.
Conclusion: Which Smart Pet Door Is Right for You?
After three months of testing, the best smart pet doors in 2026 come down to a few clear winners. The Power Pet PX-2W is my top pick for large dogs thanks to its steel deadbolt lock and four-way access control. For cat owners who want app connectivity, the SureFlap Microchip Pet Door Connect delivers remote monitoring that genuinely improves daily life. And the Cat Mate 360 remains the best budget option for microchip scanning without breaking the bank.
Your choice ultimately depends on your pet’s size, your installation needs, and whether you want app-controlled features. Any of these eight doors will give your pet safe independence while keeping unwanted animals out. Pick the one that matches your household, invest time in training, and you will wonder how you lived without a smart pet door.
