Hi Matcho,
I guess it's about quick,humane euthanasia. You are right, 1080 is legal so are anticoagulants as used in rat products.
Neither are humane IMO. just because they are legal does not make them right.
I would rather trap and humanely euthanase or shoot them. If like me you had seen a cat die over 24 hrs seizuring and in extreme pain after the owner gave it a panadol because it wasn't well then give it a second because the first one didn't work (!!!) then you may undersatnd my perspective a little more.
Part of being "enlightened" and "civilized" should be reflected in how we treat all animals both friends and foe.
I guess seeing how we treat each other as human beings that I am asking too much ??
This is not meant as a criticism, rather just food for thought.
I hope you manage to get rid of them and you get to enjoy your birds (without fear) again
Myzo
