Here's why the Internet is completely overrun with cat videos, Instagram photos of dogs, and Facebook walls full of baby photos.

There's actually a scientific reason why you can't resist sharing those things.

A new study out of Yale found that when we see something cute, our bodies are wired to lose control and become overwhelmed by our desire to share the cuteness.

So when you see a cat video, you feel a strong biological urge to spread it around.

And that urge is so strong it overrides our usual inhibitions, so even people who you'd normally think are TOO COOL to lose their minds over puppies or babies can't resist sharing them.
