Stray cats are part of life in Sharjah neighbourhoods, and a manual cat flap is an open invitation to all of them. Owners tell the same story: strange cats slipping in at night, eating the food, spraying the walls, and picking fights with the resident cat in its own hallway. A microchip cat flap ends that story. It reads the implanted chip under your cat’s skin and opens only for the cats you register. Every other cat meets a locked flap.
The technology is simple and proven. The reader sits in the flap frame and scans for a chip each time an animal pushes against it. Your cat’s chip is learned once during setup, and from then on the flap unlocks in a fraction of a second for your cat and stays shut for the aggressive tom from three villas down. No collar tag to lose, no magnet to swallow, nothing for the cat to wear at all.
How the chip reader works
Almost every pet cat in the UAE is already microchipped, because vets chip kittens as a matter of routine and municipalities expect it. The chip is a tiny capsule under the skin between the shoulder blades, and it carries a unique number. The flap’s reader scans for that number when a cat presses against the flap, compares it with its registered list, and releases the lock only on a match.
Registration takes a couple of minutes per cat. You put the flap in learn mode, coax the cat through once, and the chip number is stored. From then on the flap recognises that cat every time. If you adopt a second cat later, you register the new chip the same way, and the flap opens for both while the neighbourhood strays stay outside.
Why Sharjah homes choose microchip flaps
Food theft is the complaint we hear most. A confident stray learns the sound of a manual flap within days, and once it knows there is premium cat food on the other side, it becomes a regular visitor. Spraying follows, then fights, then vet bills. A microchip flap breaks that chain at the door, because the stray never gets past the first push.
Multi-cat homes benefit too. Timid cats that would never push past a bolder animal at a manual flap get their own guaranteed access, and owners stop finding mystery food going missing. Homes near colonies or feeding stations, common around villa compounds, get the biggest relief, because the pressure on the flap is constant there.
Fitting a microchip flap into glass
The installation is the same professional glass job as a manual flap. Existing glass can never be cut, so a new panel is measured, cut in the factory, tempered, and fitted with the flap mounted and sealed. The reader, batteries and electronics live inside the flap unit, so nothing extra goes into the door or the wall.
Position matters a little more with a microchip flap. The reader needs the cat to approach squarely so the chip passes through the scan zone, which means the flap should sit at a height where the cat walks through naturally rather than crouching. The survey covers this, and the installer will advise if a fixed panel suits the approach better than the sliding panel.
Day to day with a microchip flap
Most cats learn a microchip flap within a day or two. The click of the lock releasing startles some cats at first, so prop the flap fully open for the first day and let the cat get used to the opening before the lock starts engaging. Treats on the far side do the rest.
The flap runs on batteries, and a low-battery indicator gives you plenty of warning before they run out. Changing them takes a minute and no tools. Wipe the sensor area when you wipe the flap, because a film of dust on the reader window is the most common cause of a missed scan.
Microchip flaps across Sharjah
We install microchip cat flaps across Sharjah, from villas in Masaar and Al Tai to townhouses in Tilal City and homes in Muwaileh, Al Hamriyah and Sharjah Sustainable City. Stray pressure varies street by street, so mention it at the survey and the installer will confirm that a microchip model is the right call for your situation.
To compare it against the other options, see our cat flap installation in Sharjah page, which sets out manual flaps, large flaps and microchip models side by side.
Registering your cats on setup day
Setup happens once the flap is fitted, and it is the owner’s job rather than the installer’s. The flap goes into learn mode, you coax the first cat through with treats, and the chip number is stored. Repeat for each cat in the household. The whole routine takes a few minutes per cat, and it only needs doing once unless a new cat joins the home.
Test the lock before you rely on it. With the flap in normal mode, push it from the outside yourself: it should stay shut. Then let each registered cat through and confirm the click and release happens for every one of them. If a cat’s chip was implanted years ago, or the cat came from a rescue with patchy records, a vet can scan the chip first to confirm it reads cleanly. A chip that does not scan cannot open the flap, so this check saves frustration later.

FAQ
Does my cat need a microchip for a microchip cat flap?
Yes. The flap reads the microchip your vet implants under the skin, usually between the shoulder blades. If your cat is not chipped yet, a vet visit for chipping comes before the flap installation.
Will a microchip flap keep out stray cats completely?
It keeps out any cat whose chip is not registered in the flap. A strange cat can push against it all night and it stays locked. The only way in for another animal is tailgating directly behind your cat, which the curfew and lock settings help manage.
Can I register more than one cat?
Yes. Multi-cat homes are one of the main reasons owners choose microchip flaps. Each cat’s chip is registered once, and the flap opens for every registered cat while staying locked for the rest of the street.
What happens if the batteries run out?
The flap runs on batteries, and an indicator warns you well before they are spent. The installer shows you where the battery compartment sits and how to change them, which takes a minute with no tools.
Is a microchip flap harder to install than a manual one?
No. The glass work is identical: a new tempered panel is made with the opening cut before tempering, then fitted and sealed. The reader and batteries sit inside the flap unit itself, so the installation day looks the same.
My cat is over 4.5 kg. Can I get a microchip flap in a large size?
Tell the installer your cat’s weight and measurements at the survey. Cats over 4.5 kg need a large opening, and the survey is where the right flap size is matched to your cat and your door.
