Discover how many feral cats live in Australia, what they do all day, and why they’ve become one of the nation’s biggest environmental challenges. Learn how these wild cats are evolving and what’s being done to protect native wildlife.

How Many Feral Cats in Australia?

Australia is home to millions of cats but not all of them curl up on the couch. Beneath the country’s vast deserts, grasslands, and forests live millions of feral cats, surviving entirely without human help. These elusive hunters have become one of Australia’s most controversial and misunderstood animals.

How Many Feral Cats Are in Australia?

Estimates suggest there are between 2.1 and 6.3 million feral cats living across Australia.
The number changes dramatically depending on rainfall and food availability. During dry years, populations may drop to around 1.5 million, but in wet years when prey is abundant the population can soar past 6 million. Unlike stray cats, feral cats are completely wild. They hunt for their own food, avoid humans, and often live deep in bushland, far from towns or farms.

What Do Feral Cats Do All Day?

Feral cats are solitary and highly territorial animals. They spend most of their time hunting, resting, or marking territory.
A typical day in the life of a feral cat includes:

• Hunting at dawn or dusk – Their favourite meals include small mammals, reptiles, birds, and even insects.
• Resting in shade during the day – They conserve energy, often hiding under rocks, logs, or dense shrubs.
• Grooming and marking – Even wild cats maintain hygiene and mark their range with scent.
• Avoiding predators – While apex hunters themselves, feral cats must still avoid dingoes and foxes in some regions.

These cats can roam over hundreds of hectares, depending on food sources and competition.

Does Australia Have a Feral Cat Problem?

Yes Australia faces a major feral cat problem.
Feral cats are estimated to kill over one billion native animals every year, including mammals, birds, reptiles, and frogs. They are one of the biggest threats to native wildlife, contributing to the extinction of more than 20 native species.

Because Australia’s wildlife evolved without natural feline predators, native animals like small marsupials and ground-nesting birds are extremely vulnerable.

Government and environmental groups have launched national control programs, including trapping, fencing, and humane culling in critical conservation zones. However, due to the cats’ adaptability and remote habitats, total eradication is nearly impossible.

Are Feral Cats Evolving in Australia?

Surprisingly, yes there’s growing evidence that feral cats in Australia are evolving.
Over generations, they’ve become larger, faster, and more skilled hunters than domestic cats. Researchers have noted:

• Longer limbs and stronger muscles for chasing fast prey.
• Improved camouflage to blend with Australia’s dry landscapes.
• Enhanced survival instincts, making them harder to trap or approach.

In essence, Australian feral cats have become a distinct wild population, shaped by harsh conditions and the country’s unique ecosystems.

 What Can Be Done?

Managing the feral cat population requires a balanced, compassionate approach. Some effective strategies include:

• Supporting desexing and containment of pet cats to prevent new feral populations.
• Backing wildlife sanctuaries and fenced reserves.
• Raising public awareness about responsible pet ownership.
• Using non-lethal control measures where possible.

Everyone can play a part from keeping pet cats indoors at night to reporting stray colonies to local councils or rescue groups.

 Final Thoughts

Feral cats are part of Australia’s complex ecological story a mix of human history, adaptation, and environmental challenge.
While they are magnificent survivors, their impact on native wildlife cannot be ignored. The future of Australia’s biodiversity depends on cooperation between scientists, communities, and cat lovers to find humane and effective solutions.

Key Takeaways

• Australia has 2.1–6.3 million feral cats, depending on conditions.
• They spend their days hunting, resting, and surviving in the wild.
• Feral cats pose a serious threat to native species.
• Evidence suggests they are evolving to thrive in Australia’s environment.
• Responsible pet ownership is essential in reducing their spread.

FAQ

Q1: What’s the difference between stray and feral cats?
A stray cat is a domestic cat that’s lost or abandoned but still used to humans. A feral cat is completely wild and avoids human contact.

Q2: Where are feral cats found in Australia?
Everywhere from the desert outback to tropical forests and even remote islands.

Q3: How long do feral cats live?
Most live between 3–5 years, though some survive longer in resource-rich areas.

Q4: Can feral cats be domesticated?
Kittens under 8 weeks may be socialised, but adult feral cats rarely adapt to living with humans.

Q5: Why can’t feral cats just be removed completely?
Their wide range, rapid breeding, and survival skills make complete eradication nearly impossible.
