Cat Proof Window Grilles for Cats in Singapore
Cat proof window grilles are specially designed window grilles that prevent cats from squeezing through or falling out of windows, especially in high-rise HDB flats and condominiums in Singapore.
Cat proof window grilles differ from typical child safety grilles as they use much smaller bar spacing to prevent cats from escaping. They are an important safety feature for cat owners who want to keep the windows open without without putting their pets at risk.
We manufacture, supply & install mild steel slim window grilles in Singapore that are for cats & pets safety. Using small narrow gap spacing of only around 1.5 to 2 inches, our slim grilles help to keep your cats safe and prevent them from escaping through your windows. Not only that, our slim grilles are modern and attractive, they give you good view of outside and let in bright daylight despite of having extra bars to keep your cats safe.

Cats love high places
In Singapore, many of us live in high-rise buildings - HDB and condominiums. Cats are natural climbers, they love high places. However they do not understand how high a "high floor" really is. There is always risk of them slipping or falling out of the windows. Fall from height is dangerous even for cats. The question is, how do you keep your windows open without putting your cat at risk?
Normal Grilles Cannot Keep Cats Safe.
Normal grilles are not reliable to keep cats safe. The window grilles that we normally see in HDB and condos are designed for child safety, not pet safety. Cats have very flexible body. If the gaps between the bars of the grille are too large, the cats that will attempt to squeeze through.
To prevent this, the gap between the bars has to be very close. More bars are needed to achieve this, you will end up with window grilles with excessive numbers of thick bars which look ugly. The thick bars also obstruct your view, reduce daylight and give poor ventilation. You feel like being caged in your room.
Cat Proof Window Grilles with Slim Bars for Safety and Aesthetics
Our slim window grilles will fix this problem. Using slim mild round steel bars only around 6mm thick, you can place many slim bars closely together to create gap spacing as small as around 1.5 to 2 inch to prevent cats from escaping. And yet even with more bars, the grille still look attractive and stylish.
Slim bars mean light, air, and views still flow
Even having many bars for cat safety, our slim grilles make a big difference:
1.Daylight still enters your home. Plenty of natural light still comes into your room, keeping your space bright and comfortable throughout the day. The room will not feel dark despite of having many added grille bars.
2.Ventilation remains good. The airflow is also unaffected by the slim grilles. In Singapore’s hot and humid climate, you can keep your windows open, and grilles closed, for ventilation without relying heavily on your air-conditioning.
3.Outside views are largely unobstructed. With our slim profile, the grilles do not visually block what’s outside. Your eyes can easily look past the grille bars instead of being hindered by thick bars of normal grilles.
You get good outside view without opening the grille panels, and your home stays bright and airy. From a distance the slim grilles looks disappear into the background. You get safety that your cat needs, without affecting the aesthetic of your home.

Our mild steel bars are also strong and durable. They are much stronger than aluminium, they can handle daily use and pressure without bending or weaken over time They are also provide added security to deter outsiders from breaking in. This makes slim mild steel grilles a reliable, long-term safety solution for cats and pets in homes.
Flexible Design – Sliding, Swing Open or Fixed
Our slim window grilles are available in sliding, swing open (casement) and fixed types. Cat owners & home owners can select which grille type best suits their home and lifestyle.
Sliding grilles are ideal for windows that are opened frequently, they are popular in HDB flats and condos where space is limited.
Swing open casement grilles open like a door, giving you wide full view of the outside, they are great for balconies or smaller windows (eg. master aircon window) where isn’t enough space for sliding grille.
Fixed grilles provide permanent safety barrier for your pets, they have thinner outer frames so they can flush to the wall nicely against your windows area.

Installing slim grilles isn’t just about materials. Proper spacing, alignment, and secured installation are also important. We have installed our slim grilles for many homes across Singapore. Our slim grilles are suitable for all residential (HDB flats, condominiums, landed houses) and commercial places (offices, retail shops etc).
FAQ on Cat Proof Window Grilles
1. 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.
2. What gap spacing is safe for cats?
If the cat’s head does not fit through the gap, its body usually cannot not 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.
