Cows have best friends.

Lists of the world’s most intelligent animals don’t often feature cows, but our bovine friends have more emotional depth than they tend to get credit for. A 2011 study by scientists at the University of Northampton in England revealed that not only do cows have best friends, but they also get stressed out when separated from their BFFs — a relatable quality if ever there were one. The research was conducted by comparing heart rates and cortisol levels during 30-minute sessions in which a cow was penned with a “preferred partner” it was known to have a close bond with, then a “familiar but nonpreferred individual.” When the besties shared a pen together, their heart rates were lower and other signs of stress were also reduced.

Cows aren’t the only animals that form friendships. Chimpanzees and bonobos do, too, as do several others, including dolphins, horses, certain birds, and marmots. Dolphins can identify their friends by taste, whereas most other creatures are known for simply grooming, remaining in close proximity to, and touching their besties — capuchin monkeys, for example, gently stick their fingers in one another’s eye sockets as a bonding ritual. So don’t be offended if you get Shemped.
