This shit is just silly, cute, and fucking cool. My favorite has got to be dude with the sunglasses and his hands folded. What anime is that supposed to be?
Here’s the story: the cat’s name is Guagua (“瓜瓜”) It was Guagua’s birthday celebration for which his owner, a user named toshiya86 from a Chinese blogging service Weibo (to see her page, unfortunately, you have to be registered in Weibo) drew these characters on cardboard. Characters and anime included: Christine Mi, Dino, Gold Sparkle, Kiki’s Delivery Service, QB, Green Drive, the Old Anchor, Gintama and Naruto.
