Here's ABC for a special series "Social stars." So cute. Don't be grumpy anymore. You're super cute. Aw. Reporter: It's her frown that has many cracking a smile. Grumpy cat. I love a good photo shoot, especially with such a famous star. Reporter: She's known as grumpy cat. But her real name is Tarter sauce. Nice. Reporter: And it's her signature frown that went viral three years ago and helped create what's now a booming grumpy cat industry. There was a swarm of people around grumpy within seconds of you taking her out of the bag. She handles all this fame so well. She's a diva. She was born star.

Her book has been translated into 15 languages. The grumpy plush dolls so far, 1.5 million sold. She even has a leading role in her very own lifetime movie. Are you serious? I'm serious. Look at my face. I think sometimes humans tend to shun people that don't always look the same. Honestly, I think you're right. Like grumpy cat kind of makes being different okay.

She's so cute. Never thought I would be ma managing a business around a cat. It's definitely fun and interesting. Reporter: That's Brian, Tabitha's brother. He's the man responsible for taking and uploading the photo that shot grumpy cat into the spotlight in 2012. That same photo, a mean sensation, shared thousands of times around the web, Brian is now grumpy's business manager. I used to work for the cable company and I left that about a year and a half, two years ago. And this is my full-time gig now. Full-time grumpy cat. Definitely.

But in the dog-eat-dog world of entertainment, social media is making it easier for pets to become instant celebrities. For example, Cloe, the mini frenchy who was discovered on instagram. Her posts tend to make people smile and laugh and feel good. And I think translating that to a marketing initiative and a partnership with a brand is so powerful. They want their ads to have that same effect. Reporter: That's Cloe's owner. I think six months. It really started taking off and getting brand requests every week, everything from "Vogue" to jimmy Choo to Dyson wanting to work with her that it became a little more serious. I set up an LLC for her and now she has her own company. Reporter: The more influence they have online the more money they can make. It can be anywhere from a couple hundred dollars to a post to $30,000 for a post. It's a wide range. Reporter: The demand has grown so much that come January she will be fully dedicated to managing a pet model agency. It takes a lot of time.
