The old nursery rhyme may have questioned where the pussy cat had been, but a new research program reveals that just like the moggy that went to London, Australian domestic cats love to roam.

Using global positioning system (GPS) devices, the program used at Lithgow, in central-west New South Wales, tracked the daily movements of a group of pet cats.

The results shocked some of their owners.

We all live downstream – it’s time to restore our freshwater ecosystems

In East Gippsland our freshwater ecosystems are threatened by clearfelling in most catchments, by industrial and agricultural pollution and excess nutrients, fire fighting chemicals broadcast over large areas, all of which end up in the Lakes system that is also threatened by deepening of the entrance at Lakes Entrance. This is changing a brackish-freshwater system to a marine system, killing of the unique suite of species that evolved in these Lakes. The fact that in East Gippsland we are still seeing new species of fish and crays discovered shows how little we know what is in the water, let alone how it all works. [Ed]

Freshwater covers a tiny area of the planet’s surface, but is vital for our economies, environment and, of course, our survival. Yet freshwater is also among the most threatened ecosystems, where wildlife has declined faster than in the oceans or on land.

Feral cats in Australia are descended from animals that arrived after European settlement, confirming their devastating impact on local wildlife, researchers say.
