The 5 Best Smart Pet Doors for Cats of 2026
A regular cat flap is an open invitation to every raccoon, stray, and neighbor's cat in the zip code. A smart pet door fixes that: it reads your cat's microchip or a collar tag and only unlocks for your pets, keeping the wildlife and the freeloaders outside. We compared twenty smart pet doors on selective entry reliability, installation, durability, and price. The SureFlap Microchip Cat Flap won because 18,253 reviews at 4.1 stars make it the most proven selective-entry door available, reading your cat's existing microchip with no collar tag needed, for 128.84 dollars. Multi-cat households should look at the SureFlap DualScan, big cats and small dogs at the SureFlap Pet Door, app lovers at the SureFlap Connect, and bargain hunters at the HIDROSIL collar-sensor door. Here is how each earned its place.

HIDROSIL Cat Door with Collar Sensor, 4-Way Lock
Best for
This is for the renter or the budget-conscious owner whose cat is not microchipped. The collar-sensor system gives you selective entry without a vet visit, at 54.99 dollars. The review base is small, so you are an early adopter.
Why we love it
I love that selective entry finally has a budget option: 54.99 dollars with 4-way locking is genuinely cheap for what it does. The 4.4-star rating across 35 reviews is promising, and collar sensors suit unchipped cats. Compared to the SureFlap Microchip Cat Flap, which costs more than twice as much, you trade the proven microchip system for a tag. For the price, it is a fair trade.
Pros
- Only 54.99 dollars, the cheapest selective-entry door
- 4.4 stars across 35 reviews
- 4-way locking for flexible access control
- Collar sensor works for unchipped cats
Cons
- Only 35 reviews, a small sample
- Collar tag can be lost, unlike a microchip
- Less proven long-term durability than SureFlap
Verdict
Yes if the budget is the deciding factor and your cat will wear a collar tag. At 54.99 dollars with 4.4 stars it is a reasonable gamble. If your cat is microchipped, the SureFlap Microchip Cat Flap is more reliable for about 74 dollars more.
SureFlap Microchip Pet Door Connect
Best for
This is for the owner who checks the pet cam from work. Remote locking, curfew schedules, and comings-and-goings notifications turn a pet door into a connected device. You pay 313.00 dollars for the privilege, but the features are real.
Why we love it
I love the peace of mind: knowing exactly when the cat came home, and being able to lock the door remotely when the neighborhood tomcat is prowling. The microchip reading is the same proven SureFlap system. Compared to the SureFlap Microchip Cat Flap, which is the better value by far, this is for owners who will actually use the app. The 3.8-star rating says the app experience is not perfect, so buy it for the features with eyes open.
Pros
- App control for remote locking and schedules
- Entry and exit notifications on your phone
- Microchip reading, no collar tag needed
- Larger flap fits bigger cats
- From the proven SureFlap line
Cons
- 313.00 dollars, the most expensive pick
- Only 605 reviews at 3.8 stars
- App setup adds complexity some owners will not use
Verdict
Yes if you want to know when your cat comes and goes, or lock the door from your phone. The app features are genuinely useful for anxious owners. If you do not need the app, the SureFlap Microchip Cat Flap does the core job for less than half the price.
SureFlap Microchip Pet Door, White
Best for
This is for the Maine Coon owner, the chubby rescue, or the small dog household. Standard flaps are too tight for big animals, and this is the proven large-format option with microchip security. You pay more and get a slightly draftier seal, but the cat actually fits.
Why we love it
I love that big cats get a real option instead of an awkward squeeze. The larger flap with microchip entry means your 20-pound cat gets the same selective security as everyone else. With 5,689 reviews it is well tested. Compared to the SureFlap Microchip Cat Flap, which wins on rating and price, this wins on fit. For large pets there is no contest.
Pros
- Larger flap fits big cats and small dogs
- Microchip selective entry
- 5,689 reviews at 3.8 stars
- Same trusted SureFlap platform
Cons
- 272.68 dollars is expensive
- 3.8-star rating reflects some reliability complaints
- Oversized for average cats, letting in more draft
Verdict
Yes if your cat cannot fit a standard cat flap. The larger opening is the whole point, with 5,689 reviews behind it. For average-sized cats, the SureFlap Microchip Cat Flap is cheaper, better rated, and seals tighter.
SureFlap Microchip Cat Flap, White
Best for
This is for the cat owner tired of uninvited guests. The SureFlap reads the microchip your vet already implanted and unlocks only for your cats. Installation is a standard jigsaw job, and 18,253 reviews mean every common problem has been seen and solved by someone.
Why we love it
I love the elegance of using the microchip that is already there: no tags to buy, lose, or replace. The 18,253 reviews at 4.1 stars are the largest proof base in the category, and owners consistently report the selective entry working as promised. Compared to the HIDROSIL, which is cheaper but tag-based, this is the set-and-forget option. At 128.84 dollars it pays for itself the first time it keeps a raccoon out of your kitchen.
Pros
- 18,253 reviews at 4.1 stars, the most proven in the group
- Reads your cat's existing microchip, no collar tag
- Selective entry keeps out strays and wildlife
- Straightforward door installation
- 128.84 dollars
Cons
- 4.1 stars, so not flawless, with some battery-door complaints
- White only in this model
- No app connectivity at this price
Verdict
Yes for most cat owners. The microchip system is the key advantage: nothing to lose, nothing to replace, and 18,253 reviews confirm it works. If you need app features, the SureFlap Connect is the upgrade; if the budget is tight, the HIDROSIL is the cheap alternative.
SureFlap DualScan Microchip Cat Door
Best for
This is for the multi-cat household with mixed lifestyles: one cat roams, one stays in. The DualScan reads chips on exit too, so you can allow one cat out while keeping the other inside. It is a niche problem, but if you have it, this is the only real answer.
Why we love it
I love a product that solves a problem nothing else touches. Exit control per cat sounds like a small thing until you have spent a year trying to keep one cat in while another goes out. The 2,442 reviews at 4.0 stars show it works for real multi-cat homes. Compared to the SureFlap Microchip Cat Flap, which only controls entry, this is the specialist. Worth every penny of the 205.06 dollars if you need it.
Pros
- Reads microchips on both sides of the door
- Keeps indoor cats in while letting chosen cats out
- 2,442 reviews at 4.0 stars
- Solves the multi-cat problem nothing else does
- No collar tags needed
Cons
- 205.06 dollars costs more than the basic SureFlap
- 4.0-star rating with some setup complaints
- Programming multiple cats takes patience
Verdict
Yes if you have both indoor and outdoor cats, which is the exact problem this solves. Nothing else in the group controls exit per cat. For single-cat homes, the SureFlap Microchip Cat Flap does entry control for less.
Frequently Asked Questions
Will a microchip door read my cat's chip?
Most microchip doors work with the standard 15-digit chips vets implant, including the common FDX-B type. Very old or non-standard chips can be an issue, so check the door's compatibility list. When in doubt, your vet can tell you which chip your cat has.
How long does it take a cat to learn to use one?
Cats usually learn within a few days to a couple of weeks. Most doors have a training mode that leaves the flap unlocked so the cat gets used to pushing through. Treats on the other side speed things up considerably.
Can raccoons or stray cats get in?
That is exactly what selective entry prevents. The door stays locked until it reads your cat's registered microchip or collar tag, so raccoons, strays, and neighbor cats cannot get in. It is the main reason to buy smart over a basic flap.
What size pet door does my cat need?
Measure your cat's shoulder height and width, then compare to the flap opening dimensions, not the overall door size. Your cat needs to pass through comfortably without crouching hard. When between sizes, size up, especially for long or fluffy cats.
