For the last few days I can smell wee wee in the main bathroom, it's a sunny room so the smell has got worse over the last few days! ( it's not hubby before you say (a) he's away (b) he doesn't use that toilet. ) The girls often go in this room and sun bathe, I am not completely sure who it is but I suspect it is Lottie as she has been a sprayer (territory) before. I have scrutinised every inch of the bathroom on my hands & knees trying to spot some kind of mark or find the exact location, I have washed with every cleaner going but there is still a faint aroma, so I have Biotex on order with Amazon. It's a an old wooden floor too which is not good. Any ideas? Need to get this resolved before my husband gets home, I can't blame this on his dogs as they are not allowed to go up stairs. Help!
