5 High-Powered Animal Celebrities Who Earn More Than You Do In the wake of swirling reports about Grumpy Cat's enormous earnings, we thought we'd check in on a few other animal celebrities who have managed to not just cultivate an Internet following, but cash in on it.

On Sunday, the British tabloid The Daily Express made headlines the world over with its report that Internet meme sensation Grumpy Cat (née Tardar Sauce) had earned approximately $100 million since fall of 2012, when a picture on Reddit kicked of a whirlwind transformation that quickly turned a then-unassuming household cat into an established Internet celebrity.

While Tabatha Bundesen, Grumpy Cat's owner, has since called The Daily Express report "completely inaccurate" (she declined to reveal her cat's actual earnings) it's safe to assume that frown-y feline has amassed a small fortune. After all, the past couple years have been insanely busy ones for Grumpy Cat: There's the line of licensed merchandise, two books, and a just-released Lifetime TV movie (Grumpy Cat's Worst Christmas Ever), plus frequent appearances on talk shows, including The Today Show and Good Morning America.

From its inception, the Internet was made for the ogling of cute animals. That part hasn't changed, but just as with human YouTube stars, over the past few years a burgeoning rank of pet A-listers has begun to emerge out of the endless sea of no-name (if adorable) kittens/dogs/guinea pigs, etc. prancing it up on social media. Grumpy Cat's manager Ben Lashes -- who has made a career out of managing famous cats (other clients include Keyboard Cat and Nyan Cat) – recently made this human celebrity comparison explicit, telling Spin: "These cats will be respected like real-pop cultural icons and that's cool."

Starting with Grumpy Cat (the Justin Bieber of the bunch?), here are five animal social media sensations who have managed to translate online fame into offline deals.

Grumpy Cat

Grumpy Cat's permanently unimpressed expression can be attributed to the fact that she was born with feline dwarfism, which gives her a noticeable underbite.
