While I was hospitalized & then home but immobilized, my daughter decided to add a number of strays to our then household of 5 cats (now down to 4). The strays apparently didn't know what a litter box was & the resident cats soon followed suit, with my teen only cleaning up rather lackadaisically. The resident cats now use their box faithfully, so resoiling is not a problem. I pulled the already horrid 70's era carpet, but the smell is still STRONG (luckily we both have severe sinus problems) even after repeated dosings/scrubbings of the enzyme cleaners to the hardwood. My house is 103 yo and the floors need refinishing anyway, but don't have the $ to have it done or the abilty to hold the big sander steady right now. Since the problem is isolated to the edges of the room, would it be possible to lightly sand just the perimeter for now, dose regularly with more enzyme stuff and either leave unfinished or finish. Looks for the short term aren't that big an issue (the perimeter is hardly visible anyway), I just want to be able to refinish completely with no problems in a year or two. Any advise will be VERY appreciated, as I'd like to be able to have company without having to hand out gas masks!! Marci
