An unfortunate apartment-dweller thought she had acquired a cool new doormat when her neighbors moved away. Instead, she discovered, she'd acquired a patch of dog urine.

Redditor Ellieohsnap posted a photo of the offending "doormat" to Reddit on Saturday, along with a note from her otherneighbors — the ones who filled her in on the truth.
