Installing a cat door for window openings — or a window pet door for cats and small dogs — is often the smartest way to give your pet access to an enclosed balcony, catio, or villa garden when your main patio doors are heavy or obstructed. Across Dubai, Abu Dhabi, and all seven emirates, we supply and fit both removable sliding window inserts and replacement factory-tempered glass window panels.
Two Routes: Cat Door for Sliding Window Inserts vs. Factory-Tempered Glass Window Panels
1) Removable Cat Flap in Window Insert: If you have horizontal or vertical sliding windows (common in kitchens, laundry rooms, and apartment balconies), we fabricate a slim powder-coated aluminium cat door for sliding window tracks. It locks into the window channel without cutting glass or drilling frames. 2) Replacement Glass Window Cat Flap: For fixed or hinged casement windows — including double-glazed units — you can never cut existing toughened glass on site. Instead, we laser-measure your pane, fabricate a new factory-tempered single or cat door double glazed window unit with a precision circular cut-out, and store your original glass for a 30-minute swap-back when you move.
Enclosed Balconies, Litter Box Ventilation & High-Rise Safety
An enclosed balcony is the safest outdoor space a UAE apartment cat can have — and a window flap is what makes it usable without leaving glass open to the heat. Our balcony and litter-box guide explains the layouts Dubai apartment owners use most:
Microchip & Manual Flaps That Fit Window Panels
For microchip control that reads your cat’s 15-digit ISO FDX-B vet chip and keeps stray cats out, we fit SureFlap and PetSafe microchip flaps using circular glass mounting adapters. For households wanting a simple manual dial (in-only, out-only, open, or locked), we install Closer Pets manual four-way locking flaps. Cats over 4 kg (such as British Shorthairs and Maine Coons) are fitted with a Large cat flap.
Frequently Asked Questions About Window Pet Doors
Can you fit a cat door for sliding window tracks without landlord approval?
Yes. Our sliding window insert sits inside the existing window track without drilling or cutting, and lifts out in minutes at move-out.
Can you install a cat flap in glass window panes that are double-glazed?
Yes. We manufacture a sealed, factory-tempered replacement double-glazed window unit with the flap pre-fitted, keeping your AC inside and heat out.
Do you also fit a window dog door for small breeds?
Yes, where the window opening is wide enough and sits at a safe step-over height, we can fit a Medium (23×35 cm) flap for small dogs.

Which Windows Suit a Cat Flap
Sliding windows are the easiest starting point. Kitchens, laundry rooms and apartment balconies usually have horizontal or vertical sliding windows, and those take a slim powder-coated aluminium insert that locks into the window channel without cutting glass or drilling frames. Fixed or hinged casement windows, including double-glazed units, take the second route: we laser-measure the pane and make a factory-tempered unit with a precision circular cut-out, because existing toughened glass can never be cut on site. And when the main patio doors are heavy or obstructed, the window is often the smarter route to the same balcony, catio or villa garden. Whatever the window, the rule is the same: no drilling, no cutting of existing glass, and nothing that cannot be reversed at move-out.
Sizing a Window Flap for Cats and Small Dogs
The over-4kg rule applies at windows too: any cat over 4 kg needs a Large flap, which covers British Shorthairs and Maine Coons as well as other large cats. Smaller cats are comfortable in a medium opening, and small dogs can use a Medium at 23 x 35 cm where the window opening is wide enough and the step-over height is safe. Send us WhatsApp photos of the window and your pet’s breed and size, and we confirm the size before the visit, so the right flap arrives with the fitter. The flap should sit at a height your cat reaches in one easy step, and once it is in, the balcony becomes usable without leaving glass open to the heat. That is the point of the whole job: fresh air and outdoor space for your cat, without an open window.
Fitting Day and Life With a Window Flap
The booking starts with WhatsApp photos of the window and your pet’s breed and size, or an email for a photo quote, and we confirm the route, the size and your emirate’s next visit before anyone travels. A sliding window insert lifts out in minutes at move-out, needs no landlord approval and leaves the window exactly as it was. The glass route is a two-stage job: laser measurement first, then a pre-fitted factory-tempered unit is swapped in, with the air conditioning kept indoors and the heat kept out, and a 30-minute swap-back when you move. An enclosed balcony is the safest outdoor space for a UAE apartment cat, and a window flap makes it usable every day, while litter-tray ventilation keeps the air inside fresher too. Microchip flaps fitted with circular glass mounting adapters read your cat’s 15-digit ISO FDX-B vet chip and keep strays out, and a manual Closer Pets flap gives the same four-way dial control: In Only, Out Only, Open Both Ways and Fully Locked.
