Research shows roaming pet cats collectively kill 390 million animals per year in Australia. That's an average 186 animals per cat per year.

Pet cats live in greater densities than feral cats. In the bush there is one feral cat per 3-4 square kilometre, versus 40-70 pet cats per square kilometre in urban areas; pet cats in urban areas kill 30-50 times more animals per square kilometre than feral cats. Studies have found even single pet cats have driven declines and complete losses of populations of some native animal species in their area.

Sydney Olympic Park is an urban biodiversity hotspot, home to over 250 native animal species. Predation by feral and domestic cats poses a significant threat to the Park's wildlife, especially wildlife threatened with extinction, such as the endangered Green and Golden Bell Frog.

Sydney Olympic Park Authority has a legal responsibility to protect wildlife within its jurisdiction. The Authority has developed a Cat Management Program for implementation in Wildlife Protection Areas, in accordance with the NSW Companion Animals Act 1998.

Under the Authority’s Cat Management Program, cats found within bushland, wetland and grassland habitats may be impounded and taken to a nearby holding facility where they will be checked for the presence of a microchip or other identification. If an owner can be identified, they will be contacted to collect their cat and pay a fee to the holding facility. If an owner cannot be identified or contacted, the cat will be taken to the pound.
