Even animals have ways to respond with gratitude when we treat them with kindness. They might respond to our care and affection with devotion, with help, or just with a loving gaze. At such moments, the soul feels lighter and glows with the feeling that you’ve made a positive change to the world.

Here are a few photos where people have captured the meaning of a big heart.
