Cat Proof Window Grill & Gate in Singapore – Safe Window Grilles for Cats

Cat proof aluminium window grill installed in Singapore HDB bedroom, narrow 2-inch gap design for pet safety and ventilation

We Singaporeans love our cats. With their soft fur, playful antics, and affectionate purrs, cats easily charm their way into our hearts. But being a cat owner in Singapore also means taking extra steps to ensure their safety—especially in HDB flats and condominiums where high-rise windows and balconies pose serious risks.

The safest solution? A cat proof window grill or cat proof gate. These specialised installations keep your cats safe indoors while still allowing fresh air and sunlight to flow through your home. At Ho Ho Engineering & Renovation Works, we have been protecting Singapore homes since 1976, and our cat friendly window grilles and gates are trusted by thousands of homeowners.

Why Cat Owners Need Cat Proof Window Grilles

Cats are curious and adventurous by nature. Even the most careful owners can’t always stop their pets from climbing, squeezing, or jumping. Unfortunately, high-rise falls are a real danger in Singapore.

A cat proof window grill ensures your pet stays safe by:

Using narrow vertical gaps (1.5–2 inches) that even kittens can’t slip through.
Featuring a sturdy, rust-resistant frame that withstands climbing and scratching.
Allowing ventilation and natural light without compromising safety.

Unlike DIY nets or cheap mesh screens that tear easily and don't look good, our custom-built cat proof window grill are designed to last for years while keeping your furry companions secure.

Cat Proof Window Grill Pricing

Every home has different window widths and panel numbers, so the most accurate way to calculate cost is on a per square foot (PSF) basis.

At Ho Ho, our normal aluminium window grilles are priced from $8 PSF, with bar gaps within 5 inches (≈12.7 cm). While this is safe for general use, it is not suitable for cats, as they may still squeeze through.

For cat owners, we recommend cat proof window grilles with much narrower spacing. The ideal gap is approximately 2 inches (≈5 cm)—small enough to keep even kittens securely indoors. Because nearly double the material is required, the price starts from $12 PSF onwards, depending on material choice and specifications.

Aluminium Cat Friendly Grille – starts from $12 PSF (most affordable option)
Mild Steel Slim Cat Proof Grille – premium pricing (higher than aluminium window grill for cats, worth it as it is more invisible and stronger)

💡 Example calculation:
A typical HDB 2-panel window measures 4 ft × 5 ft = 20 sq ft × $12 = $240

Our cat proof window grill designs feature horizontal or vertical bars with narrow gaps, ensuring your cats stay safe indoors while still allowing fresh air and natural light to flow through your home.

Window Grill For Cat Designs In Singapore

When it comes to cat proof window grill designs in Singapore, the narrow 2-inch gap means there are only two choices: horizontal bars or vertical bars. Both provide the same level of safety for your cats, and the choice comes down mainly to style preference.

Horizontal cat proof window grille – This is the most popular design among Singapore homeowners. The horizontal layout feels modern and blends well with most interiors.
Vertical cat proof window grille – Equally safe, but less common because some homeowners feel it gives a “jail-like” appearance.

You can also choose from a wide range of colours — from anodised bronze, silver, black, and white to fully customized powder-coated finishes. Matching the colour of your cat proof grille with your existing windows creates a more seamless look.

💡 Pro tip for cat owners: If you find the standard aluminium bars too thick or “jail-like,” consider upgrading to our Mild Steel Slim Cat Proof Grille with ultra-slim 6 mm bars. It offers the same safety but with a invisible, sleeker, more elegant appearance.

No matter which design or material you choose, every cat proof window grill is customized made and professionally installed, ensuring that your cats stay safe without compromising the look of your home.

Cat Proof Window Grill Mechanism In Singapore

When choosing a cat proof window grill in Singapore, it’s important to consider not just the design but also the mechanism. Different materials work best with different opening styles, ensuring long-term durability and ease of use.

Aluminium Cat Proof Window Grille (Sliding)

Aluminium grilles are lightweight, making them ideal for a sliding mechanism. The panels glide smoothly along the track, allowing you to open and close your windows with ease. Aluminium cat proof grilles typically have a 3-inch frame thickness, offering a strong yet practical option for everyday use.

We offer two common frame sizes for cat proof window grill:

3-inch frame – for standard 2-track sliding window grilles (most common choice).
4.5-inch frame – for 3-track sliding window grilles, typically installed in kitchens or service yards, where homeowners want to fully open the windows for laundry drying or better ventilation.

This flexibility ensures your cat proof window grille not only keeps your cats safe but also matches your lifestyle and daily routines.

Casement cat proof window grill installed in Singapore HDB BTO bedroom, slim mild steel material with narrow 2-inch gaps for cat safety and ventilation

Mild Steel Slim Cat Proof Grille (Casement)

Mild steel is much heavier than aluminium, so it is best suited to a casement mechanism (swing open like a door). Sliding rollers for heavy steel are less durable, while casement hinges provide stronger and more reliable support. Mild steel slim grilles also feature a 2-inch frame thickness, giving them a sleeker look with less protrusion into your room.

Fixed Cat Proof Grilles (Not Recommended)

Some homeowners may consider fixed grilles because they have less protrusion (1 inch), but these are not recommended. Fixed grilles make it difficult to clean your windows, and more importantly, they can block your emergency escape route during a fire. For both safety and practicality, a sliding or casement cat proof grille is always the better choice.

By understanding the right mechanism for each type of grille, you can ensure your window grills for cats are both safe for your pets and convenient for your household needs.
