Lists invasive species as a major threat.

http://wwf.panda.org/about_our_earth/species/problems/invasive_species/

IUCN, the World Conservation Union, states that the impacts of alien invasive species are immense, insidious, and usually irreversible. They may be as damaging to native species and ecosystems on a global scale as the loss and degradation of habitats.
Hundreds of extinctions have been caused by invasive alien species. The ecological cost is the irretrievable loss of native species and ecosystems.

Invasive alien species (IAS) are species whose introduction and/or spread outside their natural past or present distribution threatens biological diversity.

https://en.wikipedia.org/wiki/Biodiversity#Threats

Jared Diamond describes an "Evil Quartet" of habitat destruction, overkill, introduced species and secondary extinctions.[144] Edward O. Wilson prefers the acronym HIPPO, standing for Habitat destruction, Invasive species, Pollution, human over-Population and Over-harvesting.

Feral cats threaten the survival of over 100 native species in Australia. They have caused the extinction of some ground-dwelling birds and small to medium-sized mammals. They are a major cause of decline for many land-based endangered animals such as the bilby, bandicoot, bettong and numbat. Many native animals are struggling to survive so reducing the number killed by this introduced predator will allow their populations to grow.

Feral cats can carry infectious diseases which can be transmitted to native animals, domestic livestock and humans.

Predation by feral cats is listed as a key threatening process under section 188 of Australia’s national environment law, the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).

At the Meeting of Environment Ministers (Melbourne, 15 July 2015), Ministers endorsed the National declaration of feral cats as pests . As part of this declaration, Ministers agreed to review arrangements within their respective jurisdictions and, where necessary, to remove unnecessary barriers to effective and humane control of feral cats. Ministers also agreed to consider feral cat management as a priority in threatened species recovery programs, and to pursue the development of a national best practice approach to the keeping of domestic cats.

The Curiosity® bait for feral cats is a long-term $4.1 million project to develop a humane, broad-scale toxic bait to control feral cats in conservation areas.

I have planted a yard of grevilleas.
We used to always have birds here.

Now, there are none

if you want them outside, you need to build a a run for them. Not just let them run rampant.

Crap.

The most effective treatment against rats is to remove their food supply.

there must be a hell of a lot of stray cats to be hitting those sorts of figures
