Oh man, you HAVE to get a video of the plate-flipping thing. If it were me I'd probably serve up something like spaghetti and meatballs, let it happen, and film it. Priceless! Youtube legendary status would be assured.
As far as the other stuff, that doesn't really sound that bad. Every day (and especially at bedtime) little dramas like that play out all the time with my 3. Each night the cats have to figure out who sleeps where, and there are inevitably some disagreements about that
But no lasting hostilities. And when one cat is foolish enough to burrow under a blanket, they do so at their own risk
To a cat, the idea of something unseen moving under the blankets is just way too exciting to just let that go. And it doesn't seem to matter which cat goes under the blanket, that cat is in for somewhat of a beating by the other two.
