As it is stated in CNN International as below (26th ofApril, 2019):  

"Australia is at war -- with feral cats. By 2020, the government wants to kill two million free roaming cats, a large chunk of the total feral cat population, which is estimated to be between 2 and 6 million.
Some areas of Australia have gone even further. In the northeastern state of Queensland, there's even a council offering a $10 ($7) bounty per feral cat scalp".

They already started to kill our feline friends by airdropping poisoned sausages!
We can do something to save these innocent furballs!
