That's for the good, I've found. I once had two kitties that liked to burrow under the covers and, encountering each other, would have WWIII. I knew about it in short order!I have cat wars, too. Sheba is 'Queen of the Bed' and sometimes chases the others completely off.
I have cats beside me when I go to sleep and when I wake up. What they do after I go to sleep only they know.
