Hi, If you want to ferret proof your bed do what I HAD TO DO (they ripped a
hole in the bottom of the box spring and took to napping in the bed.  I
purchased another sheet cover that I use on the top with the the elastic
corners and put it upside down on my box spring.  Problem was solved and my
ferrets were foiled again.  Eddie (proud father of three ferrets)
