Animals Yawning: Submit Your Own! (PHOTOS)

There are a lot of important lessons we can learn from our furry friends. Here at Healthy Living, dogs have taught us how to de-stress and cats have taught us about the importance of getting enough sleep.

But, like that kitty who just keeps on scratching at the couch, we don't always listen. In fact, according to the National Sleep Foundation's most recent annual Sleep in America poll, 43 percent of Americans ages 13 to 64 say they rarely or never get a good night's sleep during the week. And 44 percent of Americans say their stress levels have only increased over the past five years, according to the American Psychological Association's annual Stress in America report. We're tired and we're stressed and it's making us sick!

But Fido and Fluffy can relate -- they're tired, too! To prove it, we've compiled some of our favorite photos of animals yawning. Hopefully they'll inspire you to catch a few extra zzz's.
