I just moved into a new home with newly done hardwood floors and am turning the pantry into a small litter room. I plan on purchasing a clear hard plastic mat the covers the entire floor but it was pointed out to me that I should make sure the sides are all sealed to prevent any accidental leakage that might occur from getting underneath the mat and ruining the floors. Anyone have any idea what I can use to seal the sides and still look kind of pretty or neat and clean at least? This is the room. The floor is 2.05 ft x 4.08 ft. Thanks!
