19 Photos That Prove Animals Are an Endless Source of Serotonin

Pets can have their happy hormone level increased by over 130% after playing with their owner for over half an hour — and the same goes vice versa. It’s impossible not to smile back when you see wondrous eyes, a curious nose, and a smile with little teeth peeking out to see if you’re already awake in the morning, asking for a pet or a belly rub.

Here at Bright Side we adore animals, and what we love even more is to share their sweetest pics with our readers!
