Best baby gates with a pet door: which ones let the cat through without leaving a hole the baby can use

What a pet door in a gate really is

Every other gate on this site is judged on how completely it closes an opening. A gate with a pet door is judged on the opposite thing: it is sold because it does not close the opening completely. That is not a criticism, it is the product. You have a cat who uses a litter box in the laundry room, or an older dog who needs to reach water, and you have a baby who has just worked out how to move. Shutting the cat out of half the house for eighteen months is a genuine problem, and a 7-inch flap at floor level is a genuine answer to it.

What the marketing will not tell you is that the pet door is a hole in a barrier that was designed as a barrier, and the federal rule behind baby gates has something to say about holes. In the US, expansion gates have to comply with 16 CFR part 1239, which incorporates the ASTM F1004 standard, and the CPSC's own guidance lists “openings that could trap a head or a limb” among the things that standard tests. We walk through the whole rule in baby gate safety standards explained. None of the four gates below publishes a statement that it meets F1004. Every one of them is sold to parents anyway, mostly in the pet aisle.

So the practical rule this page is built on: choose a pet door you can make smaller, and ideally one you can close. A cat needs the hole open for a few seconds a day. A crawling baby has all afternoon.

How we ranked these

Default weights, with one thing doing most of the work inside the toddler-resistance score: how far down the opening goes, and whether it can be shut. A gate whose pet door locks closed earns the top of that column, because it means the barrier has a second life once the cat has learned another route or the baby has learned to climb. A gate whose smallest setting is still a fixed, permanent gap does not. The full rubric is on how we choose.

Standards scored low across the board, and it dragged every total down. Not one of these four makers states ASTM F1004 compliance, JPMA certification or Baby Safety Alliance certification on the product page, so all four carry the same low standards score. That is a fair reflection of the category rather than a knock on any one gate: this is a product sold at the seam between the juvenile aisle and the pet aisle, and nobody is volunteering a certificate.

Two gates that dominate search results for this category are not ranked here. Carlson Pet Products makes the best-known walk-through gates with a 7.5 by 7.75 inch pet door, and FairyBaby makes an extra-tall version; when we checked on September 24, 2026, every Carlson gate we looked at was listed as unavailable on Carlson's own store, and both FairyBaby cat-door gates were out of stock. We do not rank what a buyer cannot buy. If Carlson comes back into stock, note that its pages state “certified by the American Society for Testing and Materials (ASTM)” without naming a standard, and ASTM does not certify products, so read that line the way we explain in the standards guide rather than as a certification.

Sizing the opening for the cat and the baby

There are three measurements that matter and the listings mix them up constantly, so here is the order to think in.

How tall the opening is. This is what your cat cares about and it is the number that varies most. Babelio's CatPrivilege I tops out at 7.8 inches and steps down to 5.3 and 2.5. The CatPrivilege II goes to 12 inches, which is why it is the one for a Maine Coon or an arthritic fifteen-year-old cat who no longer crouches. Perma's opening is 9.4 inches at full height and 4.5 at the half-open setting. Measure your own cat crouched rather than standing, and start at the smallest setting: most houses never need the tallest one.

How wide the opening is. This is the number nobody advertises, and it is the one that matters for the baby. Perma's door is 6.3 inches wide, the narrowest here. Babelio's A7 and T7 are 7 inches, the F7 is 7.5. A narrow, short opening is a poor doorway for anything with shoulders; a tall wide one is an invitation.

How far off the floor it sits. Perma is the only maker of the four that publishes this, at 3.1 inches, which means that at full open the top edge of that hole is 12.5 inches above the ground. That matters because a baby meets the world at floor level, and a gap that starts at the floor is the one they find first. Where a gate's bottom rail sits is the same conversation we have about trip hazards in pressure-mounted vs hardware-mounted baby gates.

Set the door to the smallest height your cat will actually use, watch for a week, and then leave it there. If the cat stops using it, go up one notch. Do not set it to maximum “so the cat has room” and then forget about it, because the day your eight-month-old works out that the hole goes somewhere is the day the setting stops being a convenience decision.

The two finalists, side by side

The split is clean. Babelio gives you control of the hole: three published heights and a lock. Perma gives you documentation and a price: a full extension table opening by opening, a parts list down to the adjuster bolts, a downloadable manual, and roughly half the outlay. If the gate is going up in a laundry doorway for the cat's litter box and the baby is not yet crawling, Perma is plenty. If the gate is going somewhere the baby will spend real time, pay for the lock.

Where none of these belongs

All four are pressure-mounted, and none of the four makers offers a hardware-mount version of these particular models. That puts the top of the staircase out of bounds for every gate on this page, and it is not a close call. A pressure gate holds by friction between two rubber pads; when the CPSC adopted the 2022 edition of the standard, the change it wrote up was moving the warning “You MUST install wall cups to keep the gate in place. Without wall cups, child can push out and escape” onto its own label. A gate that can be pushed out of its opening belongs in a doorway, not above a flight of stairs. The gates that do belong there are in best baby gates for stairs, and none of them has a pet door, because a hole at floor level at the top of a staircase is a hole above a drop.

There is a workable compromise if you have both a cat and stairs. Put a hardware-mounted gate at the top of the flight with no pet door, and put the pet-door gate at the bottom of the stairs or across the hallway that leads to the litter box. The cat routes around the top gate by jumping it or by using the stairs when the gate is open; it uses the flap at the bottom. That is two gates instead of one, which is annoying, and it is still the right answer.

What the certification silence means

It is worth being precise about what a missing certification does and does not tell you. Every expansion gate sold in the US has to comply with 16 CFR 1239 and the manufacturer has to issue a Children's Product Certificate saying so. What a JPMA or Baby Safety Alliance mark adds is that an independent lab checked. Cardinal Gates, North States, Regalo and Smart Retract all state something on their own pages; the four gates here state nothing, and two of them are marketed primarily as pet products, where the juvenile rule may not be what the maker was building to at all.

That is exactly why the pet-door gate is a second gate rather than the main one. Use it where the consequence of a failure is that a toddler gets into the laundry room, not where the consequence is a fall down twelve stairs. If you want a certified gate for the important openings and are happy to solve the cat problem separately, the ranked options are in best baby gates and best pressure-mounted baby gates.

Three alternatives worth pricing first

A pet-door gate is not the only way to keep a cat mobile in a gated house, and the other three routes are cheaper.

A gate the cat jumps. Most of the gates on this site are 30 inches tall, and plenty of cats simply go over one. Put a kitchen chair across the doorway at roughly that height for an evening and watch what your cat does. If it jumps, a plain certified gate is already a pet gate, and that costs you nothing and gets you a gate with a standards statement on it.

A retractable gate you roll away. A mesh gate rolls back to a 3-inch cylinder, so the cat has free run whenever the gate is not needed. The trade is that a gate left rolled up is no gate at all, which is the whole argument in best retractable baby gates.

Moving the resource instead of the cat. Litter box, water and food are the three reasons a cat needs to cross a gate at 2 a.m. Moving all three to the side of the gate the cat lives on solves the problem permanently and costs one afternoon. This is the same logic as gating fewer rooms and babyproofing them properly, which is the approach in babyproofing for crawling babies.

Installing one of these without the usual mistakes

Three things go wrong with pet-door gates specifically. First, people install them with the pet door on the hinge side, where the door flexes every time the gate swings; put the pet door on the latch side or wherever the maker's manual shows it. Second, people skip the wall cups because “it is only the laundry door,” and a pressure gate without cups creeps. Perma ships adhesive pads as well as screw-in cups, which is the renter's option, and Babelio's gates are no-drill by design. Third, people install the gate, set the pet door to maximum, and never touch it again. The general sequence is in how to install a baby gate, and the no-drill constraints are in babyproofing an apartment or rental.
