I don't have one now. We used to have one and I turned it so the opening (buttons or ties) were on the bottom of the bed not up top by the pillows. That seamed to prevent her going under the covers and getting inside the duvet. We did not get rid of it because of her, it was just getting old and I wanted something new.
Remy does get lost under the covers sometimes.
