Sheep may actually seek out plants that make them feel better. They self-medicate.
Sheep build friendships, stick up for one another in fights, and feel sad when their friends are not around.
They recognize and remember at least 50 individual faces for more than 2 years.
Unique peripheral vision: they have horizontal, slit-shaped pupils that allow them to see behind themselves without turning their heads.
Sheep are emotional creatures. The way the sheep’s brain is organized suggests they must have some kind of emotional response to what they see in the world. They can learn how to navigate out of a complex maze. The enticing sight of their fellow sheep friends awaiting them at the finish helped them reach the exit. [BBC Earth]
