A Buffalo, New York family went on vacation and hired their daughter’s high school friend to watch over their seven cats while they were gone. When the family returned back home, they found that the cat sitter had thrown a party at their house where party-goers stole over $6,000 worth of cash and jewelry, broke furniture, and left behind piles of vomit and feces throughout the house.

The cat sitter offered to return the family the $90 they paid her to watch their cats. The end of the article summed up the final problem by stating that “the cats were traumatized by the party.”
