Your neighbor’s a heartless moron who is breaking the law.
He takes the cats to the local shelter for caring people to adopt. The ones with tags are returned to their owners.
His neighbor, who is using a live trap, is doing feral cats a service.
What would you prefer? Poison, spring trap?
My neighbor decided to “take in” three cats, which meant moving them from a neighborhood where the original owner didn’t want them, to ours. (Kind of blows that territory idea) These cats used gardens as litterboxes, scratched and hissed at anyone who happened to walk across THEIR own YARD where the cats decided to hide and had feline AIDS. In the meantime the new “owner” left food out constantly which attracted rats and raccoons.
The neighbor on the other side, having enough of the stench of cat urine, used a live trap and took them to the humane society where they were euthanize. Fine with me. My indoor cat didn’t need to contract AIDS from these animals, should he sneak out the door.
Personally, I’ve seen many a cat dead on the road. You want a pet, keep it in your house, for your enjoyment, safe and sound. Your pet is your pet. I’ll take care of my own, thank you very much.
Believe it or not, it really does work. We cleared out a local condominium complex of feral cats without any of them getting shot or run over.
