I definitely would NOT do it, despite the fact that I TOTALLY agree with your 2nd & 3rd sentences...I have ZERO love for any roaming cats, pets or otherwise, & zero love
for the harm they do in my yard & everywhere else they wrongly inhabit, including spreading parasites & diseases.
For anyone with a pet cat (meaning a cat you care about, not one that you pet once a month when it shows up for food) I strongly advise you to keep it out of my yard.
I really APPLAUD Australia for doing the right thing, no matter how difficult it may be: https://www.cnn.com/2019/04/26/asia/...ntl/index.html
While personally I think paying a bounty for scalps might be a bit much, maybe that's what it takes for people to realize they can no longer let their ---- cats run loose.
