Animals like to eat. They like to eat things that aren’t food sometimes. Sometimes, those things are parts of our cars.
Something crawled up under the hood of a brand new Civic just after it was bought, crawled in under the hood lining, and chewed through one of the windshield washer fluid hoses. I ended up having to run over to a nearby parts store to find a replacement, and I happened to find a bit of hose just the right size and exact length lying on the floor next to the racks of hose that weren’t the right size.
