A new scientific breakthrough claims that rats can experience regret, a feeling that was thought to be unique to humans.

Scientists from the University of Minnesota in America carried out a study using treats to entice rats into a food station where they could either wait for their favourite meal or go to the next stop, where another treat was already available.

The rats who didn't wait showed they regretted their decision by looking back at what they could have eaten.

Professor David Redish, who was involved in the research, believes that the findings could help us understand how regret affects the decisions humans make.
