Rats Laugh When You Tickle Them

http://www.FreeScienceLectures.com

Scientists listened to animals playing and they noticed something that appeared to them to be laughter. They studied this behavior for couple of years before acturally realizing that it is laughter.

Soon they got a device which transformed higher frequency sounds to frequencies our auditory system can hear.

So they developed a way to ask these rats if they liked being tickled and the answer was definite yes!

"I am a scientist. I get paid for tickling rats."

This made me go tickle my own ratties! They returned the favor by sticking their noses in my ear.

my dog could hear the rats when they played with eachother and "laughed". I could tell cos he was sleeping and suddenly waking up adn lok at em teh ngoing over to poke em. obviously he wanted to join in too but he knew he was too big.

[Drakaen DoomBringer]

Awesome ! Can you elaborate on the frequencies used, and the way you figured how to ask them? This is important stuff!

[Nerve Damage]

haha... that's cute... I love critters, lol.

I'm curious as to how they were able to ask the rats that question.

This may sound like a silly experiment but it is only in the last decade or so that scientists and science majors have been allowed to atribute emotion to animal behavior and response.

SO CUTE! :D

[PetiteLicorne]

You're lucky, it is a good training to do the same with women.

I love my pet ratties. They are such awesome animals.

I've used bat detectors before for an ecology class in undergrad. If I ever get pet rats, totally getting a bat detector.
