A man who was blessed by the sweet attention of a kitty on a delayed train or a boy who was put in a time out where his cat joined him in his sorrow — these are only a few examples of how our furry friends can make the gloomiest days filled with smiles, serving as natural antidepressants.

Here at Bright Side, we’re sure that animals are an endless source of serotonin. Today we’ve found 17 fortunate people who got to meet a 4-pawed friend and got cheered up on a sulky day. We’d love for you to catch these positive vibes together with us.

2. “My daughter isn’t feeling well tonight, and my dog won’t leave her side.”

4. “My husband and I found this terrified dog sitting in a crate. She is now my therapy dog and helps me fight anxiety and depression.”

7. “Had a bad case at work and the clinic cat decided to comfort me.”
