Scientists claim that rats emit a sound which is very similar to laughter when they are tickled. What is even more surprising is the fact that rats enjoy being tickled.

As a group of scientists listened to animals playing, they noticed what appeared to be laughter. They studied that phenomenon for a couple of years without actually understanding that it might be laughter. One day, they decided to tickle some animals. They realized that they had to check the sounds at a very different register in order to determine what the sound, which the animals emitted, was. The scientists used special detectors which can bring very high frequencies down to the human auditory range.

The scientists made the following test. A scientist put his hand in a glass cell with rats and started tickling them. The animals enjoyed that human company. They even started playing with the scientist’s hands and followed his hands wherever the person put them.
