Tardar Sauce, nicknamed Grumpy Cat, was an American Internet celebrity cat. She was known for her permanently "grumpy" facial appearance, which was caused by an underbite and feline dwarfism. As of March, 2020, Grumpy Cat had 8.2 million likes on Facebook, 2.7 million followers on Instagram, 1.5 million followers on Twitter, and 283 thousand subscribers on YouTube. Impressive stats, indeed! Her popularity was sealed by her participation at the South by Southwest Interactive (SXSW) festival in Austin, Texas. People stood in line for hours to get their pictures taken with her, while she mostly ignored her fans.
So, what is it about cute or funny animal photos and videos that make them so appealing to humans?
We are visual creatures and our brain is biased towards visual information. This is what has enabled us to survive. The brain registers in less than a second whether we're safe (evoking positive emotional responses) or in danger (evoking negative emotional responses) by the images we see. Images that evoke positive emotional responses cause physical changes in the brain that increase resilience to stress and reinforce positive attributes like care and compassion.
We have a wealth of scientific evidence that tell us that a whole range of physical and emotional effects are triggered when we view certain images. Research shows that warm fuzzy images of animals and babies can make us happier, increase our resilience to stress and prime our brains for positive behaviors toward others like care, compassion, and helpfulness.
We know that there are many activities that will boost our mood like gratitude journaling, visualizing good things happening to us, loving-kindness meditations, and exercise. Positive videos have been found to be one of the strongest good-mood-inducers. In fact, a 2015 review of studies found that videos had a stronger effect on mood than music or several other mood-induction techniques.
Most impressive, perhaps, are the physical changes that occur in our brains. When we see images like playful puppies and cute kittens, the brain’s pleasure center is activated, and a huge surge of the pleasure hormone, dopamine, is released. Overall, our stress levels reduce, our aggression lessens, and we tend to transform into happy, cooing, caring, baby-nurturers.
