The internet lost a huge feline personality Thursday. Colonel Meow, a lovable furry dictator who ruled over his minions on Facebook has passed. His owner Anne Marie Avery, lovingly referred to as Slave Beast by Colonel Meow, let his fans know in a post Thursday evening. The Colonel had recently undergone days of medical treatment for a heart condition, and we can only assume that was a major factor in his loss.

Colonel Meow was found along the side of the road and was rescued by Himalayan and Persian Society of Los Angeles and subsequently adopted by Anne. With his distinct looks and expressive personality, Anne created the online persona of the Colonel who gave orders to his minions and demanded scotch and treaties. He became a sensation, gathering over 359 thousand likes on his page.

He will be missed.
