In the meantime public sentiment toward cats in Australia is becoming really toxic (due to the consequences of a long-term ineffective feral control program). I swear one day when the chemical baits turn out to be worse than the cats themselves the pendulum will swing hard in favor of cats once again. They really are an indispensable tool and a big part of humanities agricultural success.

FWIW I'm in favor of dropping a few billion AUD into cat control programs and deploying technologies like felixer everywhere. Up until now it's just been an underfunded borderline volunteer affair.

Maybe store some poisoned quadrotriticale?
