I wonder if this is what killed our beloved cat Eli. He was just dead one day laying in the doghouse, no apparent trauma of any kind. I can see the idiot show hog owning neighbor using a lot of baits like this.
A neighbor-kid found our cat, Ziggy, in the grass early in the morning. Ziggy was in a terrible state. Soaked (it was raining), shaking, full on hypothermia, foam on his mouth and terrified - apparently he was conscious of his surroundings still, but could not move.
Brought him to the emergency vet. Made it. But barely. Vet thought he wasn't, but we asked to try anyway. They give the cat loads of greasy puree. Rat and mouse-poison binds to that. Cost us an arm and a leg; something I thought I'd never do for an animal. But stress and full on "sunken cost fallacy - we already drove all the way, might as wel...". He made it, which makes it worth it in the end though.
Emailed all neighbors not to do this. We live in a nature-reserve, so with all the hawks, storks, buzzards, badgers and minks, it really is unacceptable. Two neighbors confined that they got some poison illegally (this is The Netherlands where no such poisons may be sold to consumers) on the internet, unaware of the risks, and harm to animals.
Me: "you were unaware of the harm that a poison for animals, does to animals?"
I'm a beekeeper, the same happens there too "Huh? Never realized that insecticide is bad for bees, thought it only worked on wasps and flies. ...".
