In Australia the well being of native species > well being of introduced species (aka feral pests). That's why, for example, there was so much controversy over brumbies population management [1]

Continued existence of native species > well being of introduced species.

Exactly, we already had a hefty share of extinctions [1], many of those due to introduced pests

(Edited for clarity: obviously not all of those animals in the linked list became extinct exclusively because of introduced species)

More accurately, an entire bird colony > a single cat.

it's easy to see how species go extinct

> Domestic cats are responsible for the extinction of numerous mammals, reptiles, and at least 33 bird species globally.8 A study published in 2013 estimated between 1.4–3.7 billion birds and 6.9–20.7 billion mammals are killed annually in the U.S. by feral and free ranging domestic cats, making them the largest human-influenced source of mortality for birds and mammals in the country.

If I understand the article correctly, house cats are considered an invasive species in Australia.
