Are Maggies Cat Proof?

HEY GANG, HAVE BEEN LOOKING INTO PICKING UP A PAIR OF USED MAGGIES IN THE NEXT COUPLE MONTHS. PROBLEM IS MY LIVE IN GIRLFRIENDS CAT "WHICH IS DECLAWED" LIKES TO USE MY PRESENT SPEAKERS AS A SCRATCHING PAD. FORTUNATLY THE POLK AUDIOS I HAVE HAVE NOT BEEN AFFECTED OTHER THAN STRETCHED OUT CLOTH COVERS IN SPOTS. IM WONDERING IF THE MAGGIES WOULD GET TRASHED OR DAMAGED FROM THE SAME ABUSE. I KNOW A GOOD WAY TO SOLVE THE PROBLEM BUT GETTING RID OF THE CAT IS OUT OF THE QUESTION. BELIEVE ME I HAVE TRIED EVERYTHING I.E. I THINK IM ALLERGIC ECT. DID NOT WORK.
