HDB Cat Ownership: What You Need to Know About Cat Ownership Rules in Singapore

Cats are one of the most popular pets in Singapore, beloved for their independent yet affectionate nature. However, if you’re living in public housing, you’re probably wondering whether you can legally keep a cat in your flat. Navigating the HDB cat ownership rules can be confusing, especially with recent policy updates. This guide breaks down everything you need to know about keeping cats in HDB flats legally and responsibly.

New Rules

For the first time, HDB cat ownership is being legally recognised under a national framework. The revised policy allows up to two cats per HDB flat, alongside one approved dog breed under existing HDB regulations.

Key points:

  • Up to 2 cats per HDB residential unit

  • Cats must be licensed, microchipped, and sterilised

  • Owners may also keep one dog from the list of approved breeds

  • Non-compliance may result in a fine of up to S$4,000

These changes are part of Singapore’s larger push toward responsible pet ownership and harmonious living in dense urban spaces.

Transition Period 

To ease into the new rules, a two-year transition period has been announced. This gives current cat owners time to meet the updated licensing and care requirements.

Here’s what you need to know:

  • If you already own more than two cats, you may continue to keep them if:

    • You apply for licences during the transition period

    • You ensure their health and welfare

  • Newly acquired cats during the transition are not exempt from the two-cat rule

  • After 31 August 2026, owners can only keep up to two licensed cats per HDB flat

This approach supports existing owners while ensuring stricter regulation of future adoptions or purchases.

What’s Required Under the Cat Management Framework

The updated Cat Management Framework by NParks/AVS includes several conditions to ensure safe and responsible HDB cat ownership.

Required Conditions:

  • Mandatory licensing of all cats through the Pet Animal Licensing System (PALS)

  • Microchipping for identification and traceability

  • Sterilisation to prevent overpopulation and nuisance behaviours

  • Cats must be kept strictly indoors

  • Owners must ensure cleanliness, quietness, and proper pet welfare

Failure to comply can result in penalties, including fines or cat removal.

Why Were Cats Previously Not Allowed?

The initial ban on cats in HDB flats stemmed from legitimate concerns. Some of the main reasons include:

  • Free-roaming behaviour: Cats often wander, leading to defecation in public areas or common corridors.

  • Noise disturbances: Mating calls and fighting can be disruptive.

  • Abandonment and stray issues: Unsterilised cats contribute to the stray population, posing public health and animal welfare challenges.

These concerns prompted strict rules, but with better public education and a formal framework, HDB cat ownership is becoming more manageable.

How to Apply for a Cat Licence

If you plan to keep cats legally under the new scheme, licensing is mandatory. Here’s how to get started:

  1. Visit the PALS platform

  2. Create an account or log in via SingPass

  3. Register each cat with the required details:

    • Microchip number

    • Sterilisation certificate

    • Photo of the cat

  4. Pay the licensing fee, if applicable (AVS may waive or adjust fees during the transition)

Licensing your cats not only protects them—it also helps authorities track and reduce stray populations.

What Happens if You Don’t Comply?

Failing to comply with HDB cat ownership regulations can lead to:

  • Fines of up to S$4,000

  • Enforcement actions by HDB or town councils

  • Eviction of pets in serious cases of neglect or nuisance

Additionally, after the transition period, unlicensed cats beyond the allowable limit may need to be rehomed or surrendered.

Exceptions and Special Cases

Already Own More Than Two Cats?

You may continue to keep them if you register them during the transition period (by 31 Aug 2026) and meet all welfare standards. This exemption applies only to cats acquired before 1 Sep 2024.

Newly Adopted Cats?

You must adhere to the new limit—no exceptions. Even during the transition, newly acquired cats count toward the two-cat rule.

Conclusion

The updated HDB cat ownership policy signals a more pet-friendly and compassionate approach by the Singapore government. While the rules are stricter and more structured, they offer clear guidelines for those who want to keep cats responsibly in urban flats.

In summary:

  • From 1 Sep 2024, up to 2 cats allowed in HDB flats

  • A 2-year grace period allows owners to licence existing pets even if they exceed the limit

  • Mandatory licensing, microchipping, and sterilisation

  • Strict limits for private premises as well

  • Non-compliance carries heavy penalties

Stay informed, get your cats licensed, and be part of a community that values both pet welfare and neighbourly living.

Why Your Cat Might Be Obsessed with the Window in Your HDB Flat

Cat looking out of window.

Many HDB cat owners have likely noticed this behavior: your feline friend spends hours perched by the window, seemingly transfixed by the outside world. This cat window obsession is more than just idle curiosity—it reflects your pet’s natural instincts, sensory needs, and environmental enrichment. Understanding this behavior can improve your cat’s well-being and help you create a more enriching home environment.

The Natural Instincts Behind Cat Window Obsession

Domestic cats are descended from wild predators. While they may now live comfortably in urban high-rise flats, their instincts remain. The window offers your cat a front-row seat to what they perceive as “the wild”—birds flying by, rustling leaves, people moving around, or even insects crawling on the glass.

 

Cats are hardwired to observe and respond to motion. Watching the outdoors satisfies their prey drive in a non-threatening way. In many cases, cat window obsession is a form of mental stimulation, keeping them engaged with their environment in a safe manner.

Visual and Auditory Stimulation: A Sensory Feast

From an HDB window, your cat can take in a rich tapestry of sights and sounds. This includes birdsong, traffic noise, and distant human voices. Urban cats may lack the natural stimuli available to outdoor cats, so a window becomes a crucial sensory outlet.

Unlike humans who tire of repetitive views, cats often enjoy the predictability of their environment. They’ll return to the window repeatedly to check on their “territory.” If a pigeon flies by every day at noon, your cat will likely be waiting.

 

Cat window obsession may intensify when there’s consistent or recurring outdoor activity. For example, if your flat overlooks a garden or playground, the daily motion can become a key part of your cat’s routine.

Boredom and the Need for Enrichment

Indoor cats are more prone to boredom if their environment lacks stimulation. Without opportunities to climb, play, or explore, cats may become lethargic or exhibit behavioral issues. A window view provides entertainment, reducing the risk of stress or depression.

In small HDB flats, space is limited, so vertical environments like window perches become even more essential. These spaces offer both a literal and metaphorical escape from the ground-level monotony. A consistent viewing spot supports a structured routine that cats find comforting.

 

If your cat displays signs of cat window obsession such as frequent vocalizing at the window, pawing at the glass, or ignoring toys in favor of the window, it might be time to reassess their enrichment setup.

Territory Surveillance and Safety

Cats are territorial by nature. Even though they stay inside, they still “monitor” their environment. Sitting by the window is a way for your cat to observe what’s going on in their perceived territory. In HDB flats where the only external access is a window or corridor grille, cats treat that as their boundary.

 

This type of observation allows your cat to feel in control. They aren’t passive indoor pets—they’re alert guardians. The cat window obsession is linked to this desire for vigilance. It’s common for cats to respond with alert posture or vocalization when a strange animal or bird appears.

Sunbathing and Comfort

Beyond curiosity and instinct, a big part of cat window obsession comes down to comfort. Cats love basking in the sun, and windows are often the sunniest spots in an HDB flat. The warmth from sunlight provides physical comfort and helps regulate body temperature, especially in air-conditioned homes.

Sunbathing also supports vitamin D synthesis through grooming. While cats don’t absorb vitamin D directly through their skin, they accumulate it in their fur and ingest it through grooming.

 

A cozy window perch offers both heat and a calming view, creating an ideal relaxation zone. This explains why your cat may spend hours napping in the same spot.

Addressing Potential Concerns

While cat window obsession is generally healthy, there are a few things to be cautious about:

  • Window Safety: Ensure that your window grilles or meshes are secure to prevent accidents, especially on higher floors.

  • Overstimulation: Some cats may become anxious or frustrated if they see things they can’t interact with (like birds or other animals). If your cat becomes agitated, consider adding curtains to partially block the view or providing alternative distractions.

  • Sun Exposure: Prolonged sunbathing without movement can lead to overheating, especially in sealed HDB units. Provide shaded areas nearby so your cat can retreat if needed.

How to Enrich Your Cat’s Window Experience

If your cat is already drawn to the window, enhance that experience with a few small adjustments:

  • Install a cat hammock or window perch to give them a stable viewing point.

  • Add a bird feeder outside (if your unit allows) to provide safe, natural entertainment.

  • Rotate toys nearby to keep their interest focused on the area.

  • Play nature sounds or cat-friendly videos when the view is quiet or dull.

  • Give them access to multiple windows if your flat layout allows, to prevent boredom.

These additions can balance your cat’s environment and make their cat window obsession a productive outlet rather than a compulsive behavior.

Conclusion

Your cat’s cat window obsession is a combination of instinct, sensory enrichment, and emotional comfort. By offering a window view, you’re catering to their natural behaviors and improving their indoor life—especially important in compact HDB flats.

Paying attention to your cat’s environment and responses can go a long way in ensuring their emotional and physical well-being. A curious cat at the window isn’t just daydreaming—they’re thriving.
