Stray cats are a longstanding problem in Australian towns and cities. Common complaints about roaming cats include nuisance (fighting and urinating), disease risks to humans and other animals, and predation of native wildlife. The huge numbers of cats and kittens taken in by animal shelters and council pounds are a challenge to manage, leading to an estimated 50,000 being killed each year—most of them young and healthy.

Our reveals Australian council pounds, rescue groups and animal welfare shelters took in 179,615 and kittens in 2018-2019. Of these animals, 5% were reclaimed by owners, 65% rehomed and 28% killed.

Council-operated pounds killed 46% of all cats and kittens admitted. Shelters killed 25%. One in four council pounds in New South Wales and Victoria killed a staggering 67-100%.

Despite the scale of this killing, Australia's stray cat numbers are not decreasing. The evidence shows an urgent need for proactive offering free desexing of cats in targeted problem areas.

Killing so many cats is bad for people too

High cat-killing rates also have a significant human cost. Many council, and staff when required to kill large numbers of healthy cats and kittens, often repeatedly. These impacts include trauma, depression, substance abuse and .

Members of the public can also be when the stray cats they are feeding are trapped and killed.

Current approaches are failing

To make matters worse, trapping and killing stray cats and kittens is costly and has not worked. This reactive approach has not reduced the stray cat population over the decades it has been applied. Therefore, the potential nuisance, disease risks and native wildlife predation have not been reduced.

Our research shows cat intakes actually increased at municipal pounds in NSW from 2016-17 to 2018-19 (pre-COVID data are most accurate). Attempts to adopt and kill our way out of the stray cat problem have failed.

Australian councils are increasingly adopting mandatory cat containment (curfews). It seems like a logical solution, but based on the evidence it is not effective. It doesn't reduce stray cat numbers in the short or long term, as of councils such as and in Victoria.

acknowledges:

"Overall, councils with cat containment regulations have not been able to demonstrate any measurable reduction in cat complaints or cats wandering at large."

In , , and councils in Victoria have rejected mandatory containment. Their decisions cited reasons such as it is ineffective and unenforceable because most stray cats don't have an owner to contain them.

Cats may be owned, semi-owned (people feed them intentionally) or (uncommonly) unowned. In the latter case they get food unintentionally provided by people, such as from bins.

Even for owned cats, containment is due to factors such as housing limitations, cost—containment systems typically cost $700-$2,000—and concerns about the welfare of confined cats. Mandatory containment creates a barrier to semi-owners adopting the stray cat they are feeding and also potentially criminalizes cat ownership for disadvantaged families, particularly those in rental properties.

Containment to their owners' properties should be strongly encouraged where cats' physical and mental needs can be met. But mandatory containment should be rejected. It will not protect native wildlife, the commonly cited justification, because it does not measurably reduce the number of free-roaming cats.

Stray cats are not feral cats

Based on and , stray cats in urban and urban fringe areas are all domestic cats.

They are not . Feral cats , not in cities or towns or near people, are not the subject of nuisance complaints and are . Stray cats are sometimes mislabelled as , which prevents effective solutions to the stray cat problem.

Stray cats account for 80-100% of admissions to and 60-80% to . The rest are mostly cats given up by their owners.

Most stray cats entering pounds and shelters are from poorer areas and are . The people who feed them do not see themselves as owners of the stray cat but have an emotional bond with the cat.

So what's the long-term solution?

Assisting semi-owners and owners in disadvantaged areas to desex their cats is the best long-term solution to the stray cat problem. The is an evidence-based approach that supports cat owners and semi-owners with free desexing and microchipping of the cats they are caring for. These efforts should be focused on areas of high cat intakes and complaints.

Proactive are to reduce the number of stray cats and unwanted kittens in targeted areas. They thereby reduce nuisance complaints, cat intake and killing, trauma to people, costs, disease risks and wildlife predation.

Banyule in Victoria set up a free program to desex, microchip and register owned and semi-owned cats, with a focus on suburbs with high cat-related calls. In just three years, the council by 61% and numbers killed by 74%. In contrast, after Yarra Ranges Council in 2017, there was a 68% increase in impoundments in the third year.

The 2022 NSW recommended community cat programs, consistent with a "" approach. The aim is to optimize and balance the well-being of people, animals and their social and physical environment. Earlier this year, the NSW government in funding for community cat programs and facilities.

of cats entering pounds and shelters are kittens less than six months old. These figures highlight why community cat programs are urgently needed across Australia to protect cats, native wildlife and people.
