In general we find it only necessary to cut the long edges off and very rarely do we do that. UNLESS YOU ARE ABSOLUTLEY POSITIVE IT NEEDS TO BE TRIMMED, AS IN MEASURED 10 TIME AND STILL TOO LONG, DO NOT CUT IT. We find the FFR cut pretty good where it needs to fit right. The rear wall pieces are especially like this. It looks like they fit poorly until you get them in the right place. We butt the area where the tunnel meets the front and rear wall and let the floors overlap the side pieces by about a quarter inch. The front part of the tunnel we never trim the footbox pieces, we never trim the front wall, and only slightly trim anything else. The dropped box we trim around the new cage (if you have it). If you have the new cage the sides we just push in behind and glue the edges. On the back wall make sure it is in perfectly lined up with the tunnel. Otherwise the tunnel will not fit right. We trim around the door latches and when finished all you see is the chome catch, the rest is covered. I hope this helps. I need to have more pics on the site but I just don't have time. Cheers Richard.
