I am just so sorry you are dealing with this - it is my nightmare as well. For different reasons, our home was slowly destroyed by cat urine. Two aging cats developed cancer and one was in kidney failure. Room by room was ruined. I thought the odor would never go away. Now, those two have gone to RB and we have all new carpet and what do I do? Wait one day and get two kittens - now a 3rd adult cat. I dread the day when one or the other deciddes to mark something

The odor can be cleaned up with work. Lots of bacteria liguid. We removed some baseboards and pieces of carpet, etc, It is heartbreaking I know.

I really do hope things are looking up for you. I really do feel sad about this.
