Apparently a hoax. Grumpy Cat doesn't have a Hollywood star. This is just a picture of him next to someone else's star with the name changed. I like the idea of Tardar Sauce aka "Grumpy Cat" having his own star!
LOL I wish I had a cat.I wish I had a cat-door. We have 3 outdoor working cats (we do, after all, live in the country) and nobody comes inside. But a cat-door could ALMOST talk me into letting them inside.
