Rats, Rats Reget Too

Researchers at the University of Minnesota have found that rats have regrets like humans too. As explained in detail on wired.com, rats who passed up delicious treats only to find less desirable treats showed signs of regrets.

Researchers set up a contraption called a “restaurant row.” The rats could pass up on good treats and go on to the next. When they found what they were not expecting, they looked back with regret and showed other signs of regret. Kind of adds a new meaning to the expression, “Rats!”
