What happens when Grumpy Cat gazes upon a full moon? Well, she frowns at it first–I mean, she’s called Grumpy Cat for a reason–but then both the moon and her eyes turn blue. It’s a scientific fact. Don’t question it. Anyway, this officially licensed Grumpy Cat mug depicts the nocturnal event otherwise known as the “Grumpy Cat Blues.” When you add in some hot coffee or tea, the moon and Grumpy Cat’s eyes all turn blue. Why are there three Grumpy Cats, you say? Well… three times the adorable grumpiness? You got me on that one.
