Colonel Meow has 9-inch (23-centimeter) hair.
That's good enough to put the Himalayan-Persian mix into the 2014 edition of the Guinness World Records book, due out Sept. 12.
Owners Anne Marie Avey and Eric Rosario, of Los Angeles, say the 2-year-old cat got its name because of his epic frown and fur. It takes both of them to brush the cat's fur three times a week.
Three independent veterinarians verified the length of the colonel's hair and submitted their findings to Guinness before he won the title.
Avey says the 10-pound (4.5-kilogram) cat has his own website, Facebook page and YouTube channel with more than 2 million views.
Avey says there's one other thing Colonel Meow does quite well too: He sheds up a storm.
