Grumpy Cat has taken time out of her busy schedule to appear on WWE Raw.
Before the show, many WWE Superstars got the chance to meet Grumpy Cat, including Tyson Kidd.
And John Bradshaw Layfield.
Then Grumpy Cats big moment came when she was introduced by The Miz and his stunt-double Damien Mizdow.
But Grumpy Cat wanted nothing to do with them.
Which lead to The Miz losing his cool.
But he later apologised because even The Miz is a huge fan of Grumpy Cat.
