My cat has never responded to anything coming out of speakers ever before. This had her looking on all sides of the speaker trying to figure out where it's coming from. How odd. Five stars for that. Otherwise it would be a one.
Maine coons are chatty. Mine has created a proto-language out of varying meows which is exact enough to allow us to determine exactly what he wants by listening to him.
Yeah, they can get pretty noisy when they really want something and aren't getting it. In this case, the owner thought it would be funny to film the cat's reaction at not being immediately let out of the house.
