Many of you who follow Chinese history and philosophy know about Ying Yang, which is basically a symbol that represents how opposite forces may be complementary and interdependent as well as the way they may lead to each other. The picture of the two cats sleeping will ring something when someone who has some recollection of Chinese philosophy sees them. They form a pattern that resembles the Yingyang symbol and it is a beautiful thing to look at. Just like the philosophy suggests, they seem to be interdependent and interconnected as they enjoy beautiful serenity.
If you have watched This Must Be The Place, this image should help you deduce the similarity with ease. It includes Sean Penn, who stars in the movie. The cat on the right seems to have close similarity with the looks of Sean Penn on the left. This is especially so when you consider their eyes and how they both have positioned their heads facing up. I think Sean would find this a bit hilarious.
