We let Achilles to sleep with us sometimes and we have not crushed him. He loves to cuddle up right next to us when he sleeps. So, there have been times when my hunny has almost crushed him, but Achilles always is aware and moves over. I have found that he really likes to burrow, so majority of the time, he sleeps between our legs. We make a little cradle for him, with one leg straight and the other bent and he sleeps right behind our knees. It is too funny!!!
