Even when Kittens get into a little mischief it's impossible not to smile. Of course, you may not think it's funny when they are ripping up your furniture with their razor-sharp nails, but it won't be long before their silly antics charm you back into a good mood.

Not only will the videos below put a smile on your face, they may convince you to go adopt a cat. After all, Purina reports that cats can help calm our nerves and improve our overall well-being. That's right, spending time your feline friend, whether it's a kitten or a full-grown cat, reportedly increases your production of serotonin, a chemical that boosts your mood and relieve a little stress.

Knowing that may make it a little easier to deal with the scratched furniture and daily litter pan changes.

Are kittens better than chocolate?

The cat lovers in this video were told they were going to be taste testing chocolate. Instead, they opened their boxes to find a kitten inside. Their reaction confirms that chocolate is great but kittens are awesome. And zero calories — that's a big plus.

Just try to keep up with these kittens

Just try to get a group shot with an entire little of kittens —it's nearly impossible unless they are sound asleep. How cute are these little guys? They're moving around so fast it's hard to count them.

Free entertainment

There's nothing like a new toy to help keep kittens entertained.

It is impossible not to smile when you see the little guy (or girl?) on the right get startled by the toy. So cute!

Emma Watson makes us like cats more than we already do

Actress Emma Watson did an amazing job playing the role of Belle in Disney's Beauty and the Beast.

Now she's doing an equally amazing job convincing us that we should all have more cats in our lives.

Never underestimate the power of a cute kitten

Just a few minutes watching these adorable little mischief makers is a nice break from the daily grind. Now, keep in mind, while kittens are simply irresistible, there are countless grown cats sitting in shelters waiting to find a loving home.

Of course, everyone wants to take a cute kitten home, but adult cats can provide just as much entertainment, love, and stress relief as a bitty little kitten.

If you're not sure where to adopt a cat, many pet stores like PetCo and PetSmart host pet adoption events. You can also try searching the Pet Finder website or contact your town's animal control officer to get the details about cats that are in need of a good home.
