So here's where I'm confused. I've never in my life smelled milk smell that way and trust me I have kids I know what bad milk smells like (in rugs in cars in bottles and cribs) it NEVER smelled like cat piss to me before and I've always been able to clean the smell out. I also know the woman who rented our apartment before us owned three dogs and other multiple pets, I've been told she was a complete slob and was evicted. My landlord no longer allows pets. So when I called my landlord he said it sounds like the enzymes in the milk are causing the smell. Our apartment was totally renovated in between the pet lady and us but I don't think the outside hallway was ever redone.
My question is does this sound like the milk caused the smell or do you think the carpet being wet is bringing out old pet urine? My landlord is supposed to be here tomorrow I don't want him trying to blame me for this because I'm almost positive it's from the previous renter letting her pets piss everywhere.
