Protecting native fauna from our feline friends

New Zealanders have the highest rate of cat ownership in the world, but unfortunately our feline friends are a major contributor to native biodiversity decline. Researchers from Manaaki Whenua - Landcare Researcher have reviewed current research on the impact and management of cats in Aotearoa and overseas. They say more research is needed to develop improved methods for monitoring cats and their impact on our environment, and to develop humane, effective, and socially acceptable methods to manage them. There's also a need to understand any unintended consequences of cat management, such as the proliferation of pests that they prey on or compete with.

Manaaki Whenua – Landcare Research media release – The naming of cats

Fans of the musical Cats will know that the naming of cats is a difficult matter, and that cats have three different names. The same is true of cats in New Zealand – there are three types: companion or pet cats that live with people and rely on them for their welfare, stray cats that may rely only partly on people for food and shelter and live around centres of human habitation, and feral cats that have minimal or no reliance on people, and that survive independently of the companion cat population.

New Zealanders love their companion cats: we have the highest rate of cat ownership in the world and – as shown above – cats are embedded in people’s lives and culture. But cats are also a significant problem for our native fauna. Globally, cats have been implicated in the declines or extinctions of more species than any other invasive predator.

Any research into cat control, therefore, has to carefully balance their high value as companion animals with the harmful effects of cats on native wildlife and also – particularly through cats’ transmission of toxoplasmosis – on human and animal health.

However, there are currently significant knowledge gaps on the impact of all three types of cats on the environment and on the best ways to monitor and manage them. As a starting point, Manaaki Whenua - Landcare Research’s wildlife ecologists have undertaken a comprehensive review of current knowledge and research needs, published in the NZ Journal of Ecology.

Their review identifies knowledge gaps that currently prevent effective management of cats, and suggests priorities for research to address these gaps.

The priorities they identify can be grouped into four main areas:
• Improved methods for monitoring cats and their impacts.
• Developing humane, effective and socially acceptable methods to manage the impacts of cats.
• Engaging with cat owners to improve outcomes for cats, people and the environment.
• Investigating the effects of cat control on our ecosystems.

Achieving these research and predator-free goals will rely on detailed ecological knowledge, understanding current guidelines for cat ownership and management, understanding cat-human relations in a range of settings, and – very importantly – the careful creation and maintenance of social licence for any future cat management interventions
