Feral cats and stray cats are essentially the same. A feral animal is a domesticated animal released into the wild.

Just as I would advocate for killing a domesticated boar released into the wild (now feral) to wreak havoc I advocate the same for domesticated cats that are feral.

You shouldn't have removed it even if I were saying people should capture and kill invasive stray (now feral) cats, which I was, to be clear.

If you're talking about people's pets though, I would say to return them to the owner or take them to a pound.
