Nyan Cat

Nyan Cat is an animated .GIF originally created in May 2013 by Christopher Torres and Charles Schmidt [verify?]. As you can tell, the .GIF is Nyan Cat. He isn't related to Pusheen in any way. He was really made as an other Meme. Here is a compression between the original and The Pusheen One.

He has appeared in "Cats to be Thankful For", and "On the weekends I get together with Mr. Nyan Cat and trade Pokemon".
