Looking awfully proud of themselves when they dropped them, too. I wouldn't recommend it as a child-rearing practice, but I'm not prepared to disbelieve it, either. Cats do the us vs. them thing pretty well, too.
Mine have also cuddled up to us when we were upset, unhappy, or scared.
I've got a photo of my youngest daughter, late-pre-teen, asleep on my bed, with two cats and a small dog snuggled up. There are usually at least that many of them cuddled up to my wife and I most nights, too.
