If you’ve been keeping your eyes open, you might have caught a glimpse of the “cat montage” meme that has been spreading through Japan and beyond.

The gist: A human draws a set of cartoon eyes for its furry friend and creates a funny collage.

Credit for this simple yet viral idea goes to Twitter user Shirotamaaaa, who sparked the trend in early November. His original post has been retweeted more than 4,500 times.

Spilling over into Instagram and YouTube, the meme is also gaining traction overseas.
