wolf, I am also the hippo, so I am stuck where I am, as the duck has no wish to sleep on the crushed side. But if you don't actually have to share with any ducks, it sounds as though shifting to the other side of the bed and testing the springs there is the sensible thing to do. I shouldn't think the cat is fussy about which side it sleeps.
Just as well you cut and pasted the offending post before it was deleted! Otherwise we'd never know how improper it was...
