I just feel bad that the beavers' hard work was destroyed

A bag of bills stolen from a casino was snapped up by beavers who wove thousands of dollars in soggy currency into the sticks and brush of their dam on a creek in eastern Louisiana. . . . The third bag of cash couldn't be found, Martin said, so deputies started breaking down the beaver dam to drain the pond it was holding. That was when they saw the dam's expensive decoration. They eventually found the missing bag, which the beavers hadn't completely emptied."

Poor beavers. All their hard work was destoyed. I got a little sad reading this. I mean, they must have been devasted that their creation was destroyed. I think this when I vacuum up spider webs too, even though I am petrified of spiders.
