I have neutered a few over the last 10 years. I don't think he takes them and harms them; his son said he "drops them off". I don't think he would take them and shoot them then he is a monster.
My son in law takes trapped armadillos out to some woodsy area and releases them.
We have 8 cats now..7 rescues and one was kitten of a rescued cat who escaped the house once before she could be neutered. We have all we can handle..more than enough for a "full house"!
