Animals. They’ve been around for longer than us, and they’ll probably be around long after we’ve gone. Why? Because animals know the secret of life.

And what, I hear you ask, is that secret? It’s happiness. Simple, unadulterated happiness. Take a look at these pictures that Bored Panda has compiled to see just what we mean.

They aren’t smiling because they have a lot of Facebook friends. Nor are they smiling because their favorite band won Eurovision. They’re smiling because they love life. And if they don’t put a smile on your face today then we really don’t know what will!

Do you have a pet with a cheeky smile?
