Sockington (also known as ''Sockamillion'' or ''Socks'') is a domestic cat who lives in Watham, Massachusetts. By May 2009 the account had half a million followers which led British newspaper The Independent to call it ''Twitters latest megastar''. Jason Scott, a 39 year-old administrator and historian, has been posting from Sockington's Twitter account since late 2007.

Sockington has two feline companions whose Twitter voices are also provided by Jason Scott: the ginger Pennycat (aka Pennsylvania) whose posts tend to reflect ironically on Sockington and his fame, and the kitten, Tweetie, a rescue cat who looks enough like Sockington to be nicknamed his "Sockelganger".

Sockington loves his new found stardom and has been getting love letters, birthday cards and mice from other cats. Tweetie's tale of rescue has effectively brought attention to the plight of feral cats and provided an opportunity for fund-raising for The Animal Centre in Newtown, Connecticut (USA), the shelter that saved him.
