The serial cat killer doesn't have to enter the people's houses. He just drops some antifreeze somewhere near a driveway, baiting the cat to come and ingest the sweet but toxic liquid.

...but many many pet owners are quite irresponsible.

Correct. Irresponsible by NOT keeping their cats within the bounds of their premises at all times, leaving them vulnerable to the unscrupulous behavior of SCKs.

Beloved family pets should be kept in the beloved family home.

I could not sleep at night if my pets were running loose. Cats are vulnerable to all sorts of things if they are not contained (and you simply cannot keep them in a yard). It’s sad that someone is killing them, but why do people keep pets if they don’t want them secure?
