I've recently discovered a good blog named The Rambler
that delves into a lot of hoaxy material. Recently Mark (who writes The Rambler) posted a disturbing entry
about some relatives of his who let their cats run out of control:
They never cleaned the litterbox so the cats defecated all over the house. They particularly liked shoes and closets so getting dressed must have been like camping in Africa. My wife's cat makes so much noise when he's hungry that I can't imagine anyone not feeding one cat let alone 11, but they frequently let them go without food. The mother cat eventually turned cannibalistic and would wait behind furniture or random piles of crap for a kitten to walk by. When one was unlucky enough to do so, she leapt out, killed and ate it.
A cannibalistic mother cat? I'm assuming Mark isn't pulling our leg, but I've never heard of such a thing. Though I should add that my understanding of cat behavior is mostly shaped by the behavior of the one plump and lazy cat who lives with me.
