Rats are addicted to taking selfies.
Rats get a thrill from taking selfies
Paris photographer Augustin Lignier set up a study where two rodents were placed in a bespoke cage and were provided with sugar and a picture of themselves when they pressed a certain button.
Later, when the sugar was only provided occasionally, the rats kept pressing the button which resulted in the photograph and even ignored the treat when it did arrive.
Lignier argues that rats were responding in the same way that people do to being liked or followed on social media.
He told CNN: "Digital and social media companies use the same concept to keep the attention of the viewer as long as possible.
"Every time they push the button, they have dopamine in their brain and then it records the exact moment they were touching it.
"When you have such a power, when it is just with two small rats (or) billions of people, you feel like you can manipulate everything... this is a really weird feeling."
