association of above thirty noblemen and gentlemen of distinguished merit, formed in 1703, for the purpose of uniting their zeal in favour of the protestant succession in the house of Hanover. Their name was derived from Christopher Kat, a pastry cook, near the tavern where they met, in King's Street, Westminster, who often supplied them with tarts. Old Jacob Tonson was their bookseller. Their portraits were painted by Sir Godfrey Kneller.
