Colonel Meow, the fluffy gray cat with a scowling face and a dream of world domination, died on Wednesday night, owner Ann Marie Avery announced in a Facebook post.

"I will post more about the details when I've had a few days to grieve," she wrote on Thursday. "Thank you so much for your understanding, Minions. Your love and support has meant the world to us both."

Thousands of the longhaired dictator's fans replied to the post, expressing grief and offering condolences. Avery's post had been shared more than 30,000 times as of Friday morning.

Colonel Meow, a Himalayan-Persian crossbreed, was only 2 years old, but he was hospitalized in November for a heart problem.

He underwent surgery and a blood transfusion, and his "minions" raised $20,000 to cover his veterinary bills.

Although no announcements have been made about the cause of his death, there's speculation that he succumbed to heart failure.

Colonel Meow rose to Internet stardom after Avery and her husband, Eric Rosario, adopted him from a shelter and shared photos of their cat’s "epic frown" on Facebook and Instagram last year.

The fearsome feline quickly gained a massive social media following, as well as a reputation for drinking fine scotch and plotting a global takeover.

Although his life was short, Colonel Meow was well on his way to achieving world domination.

He briefly served as the CEO of Buzzfeed — where he's being feted in memorium — and he holds the Guinness World Record for longest fur on a cat.
