Our lives, or even the internet, for that matter, would look very different without pets. There would be no one to wake you up with wet kisses, steal your food when you’re not looking, or hog your pillow at night. And there would be no adorable furballs to put smiles on our faces when we opened social media after a long day.Luckily, that’s not a reality we live in, and if we need a little pick-me-up from an afternoon slump, all we have to do is visit the Instagram account ‘Your Only Source Of Seratonin’ full of adorable animal memes. Scroll down to find the best they have to offer, and don’t forget to upvote the ones that warmed your heart the most.While you’re at it, be sure to check out a conversation with Corinne Sayler, an owner of a rescue dog named River, who shares their adoption journey and training tips on their Instagram account, ‘River The Street Dog.’
