My dad is an in house lawyer for a major American insurance company. He once spent an entire year trying to help deny insurance benefits for a painter who had stepped off his ladder onto a cat, fallen down the stairs and become paralyzed. The insurance company was arguing that a cat was a commonly expected occupational hazard for a painter and that he was negligent in not checking for cats before stepping down.
A whole year of his life. Over whether a cat is a known occupational hazard of house painting.
