Doesn’t sound very “humane” to me. Seems like you ought to leave everything living if you want to treat them like we’d treat fellow humans.
I love my Husky who I got from "Canine Rescue" before he was put to death by needle because he was abandoned.
I found out why he was abandoned via compassion for life when he damn near destroyed my abode in total however being a conservative with a compassion for life, he is still alive and spoiled rotten!
He's learning to be a good conservative however and I would risk my life to protect him.
