Ranging from the smug to the foolish and the all-out Cheshire cat smiles, these adorable cats will certainly improve your day, no matter how awesome or tough it's been.

We also all know cats are mysterious, so where do these adorable animal smiles come from? Strangely enough, the ones on their faces aren't true smiles, as their facial muscles are not the same as humans. So, technically, smiling animals aren't really smiling. More often than not, your cute cat will express happiness via the obvious purring, closing their eyes, and relaxing their head backward.

Anyway, we'd love to hear which of our happy animals are your favorites, and as always, feel free to submit your own examples of smiling cats and happiness!

Is this something your friend's cat has always done? If it's something that's recently started, your friend should probably take this little furball to the vet, because it can indicate pain. (Tooth issue, jaw issue, stress, or other issues)

Millicent was the runt of the litter and would curl up like a tiny broach above my breast. She was given to me to be an indoor cat so she wouldn't be eaten by owls or eagles for a snack. Milly is currently sitting on the window sill softly meowing through the screen to a young deer eating yellow flowers on the front lawn. She hasn't yet grown into full size or her lonnngggg legs. At night, she snuggles under the covers and curls up into my abdomen with delicate purrs. "She LOVES me & i LOVE her'!
