It might be okay to eat cats on Melmac, but on Earth, it's sort of frowned upon. That's why the Tanners probably won't be very happy when you show up on their doorstep in this ALF costume, asking if you can have their cat for dinner. It looks so real though, they might invite you to live with them for a few years, where you can get into hilarious hi-jinks. Or you could just wear it to your costume party and have a great time. We're not judging either way.
