Cat Proof & Pet Friendly Window Grill Solutions in Singapore

Cat proof window grilles are specialized safety barriers designed to prevent cats from squeezing through or falling out of high-rise HDB flats and condominiums in Singapore.

Unlike standard child safety grilles, pet friendly grilles use a narrow gap spacing of 1.5 to 2 inches to keep pets secure while keeping your windows open for natural ventilation.

We custom manufacture and install mild steel slim window grilles tailored for pet safety. With 6mm slim round steel bars, our grilles protect your cats without sacrificing your outdoor view or daylight.

Cats love high places

In Singapore, high-rise living is the norm. Cats are natural climbers and love looking out window ledges, but they do not understand the danger of high floors. There is always risk of them slipping or falling out of the windows. The question is, how do you keep your windows open without putting your cat at risk?

Why Standard Window Grilles Are Not Enough

Standard HDB and condo window grilles are designed for child safety, with gaps usually around 4 to 5 inches wide. Cats have flexible bodies and can easily squeeze through these wide gaps. Traditional pet solutions used many thick bars that blocked sunlight and felt like a cage. Our slim mild steel grilles solve this by using ultra-thin 6mm solid steel bars packed closely together.

Slim Bars Keep Light, Air, and Views Flowing

Even with closer bar spacing, our slim mild steel design preserves your home aesthetic:

1. Maximum Natural Daylight: Plenty of sunlight enters your home, keeping your living area bright without feeling dark or enclosed.

2. Uncompromised Ventilation: Keep your windows open for cool breezes in Singapore's humid weather while keeping grille panels safely locked.

3. Clear Outdoor Views: From a short distance, the ultra-slim 6mm profile blends seamlessly into the background, leaving your view unobstructed.

FAQ on Cat Proof Window Grilles

Are cat proof window grilles allowed in HDB flats?

Yes. In general, the HDB regulation that applies to normal window grilles also apply to cat proof window grilles. The cat grilles should be installed inside the flat (not outside). Also, if there is no existing glass window (for example, at the service yard), HDB permit application will be required before installation of the grilles.

How small should window grill gaps be for cats?

If the cat’s head does not fit through the gap, its body usually cannot go through either. In general, gap spacing of 1.5 to 2 inch is suitable for cats. It is also the smallest spacing that we are able to fabricate for the grilles. However young kittens may be able to squeeze through, so for extra safety it is still best to keep the windows closed or keep kittens away from open windows.
