If you haven’t received this heart-warming video of an orange kitty licking a fawn, who nuzzles back, you probably will soon. In less than a month on YouTube this video, set to Louis Armstrong’s “What a Wonderful World,” has been seen nearly 5 million times.

The video was created by Saks61 on YouTube, whose profile says he is a 48-year-old Serbian named Nermin living in Germany. Saks61 hasn’t given any details on these animals, but does say that he’ll post another video soon that stars the same cat.
