We had a ferret that continually chewed on the corners of the waterbed,
causing numerous leaks.  One day as I was changing the sheets (satin
waterbed sheets), I heard an awful *crunch crunch*.  Our waterbed monster
was chewing the sheets!  Once we changed back to cotton sheets, he stopped
chewing the bed.  So maybe a change in the type of sheets would stop some
of your waterbed destroyers!
