I haven't read the info posted but I've been told that it's baker's chocolate that is supposed to be toxic to dogs and cats. I'm inclined to believe that's true because my RB dog Charmin ate a whole candy dish of chocolate covered cherries while we were at the other end of the house during the holidays. I called my vet and we watched her but nothing happened. But a pet has no business eating chocolate anyhow, so I'd make sure they didn't get any. AND...if you find out that woman is purposely trying to poison that cat, she needs to be turned in. God forbid if I live near anyone who does harm to cats.

Blessings,
