What happened to Katherine Parr when Henry had enough of her?

Catherine Parr is the one wife Henry VIII never "had enough" of, or at least he never divorced her like he did Anne of Cleves, nor was she ever beheaded. Catherine survived Henry, who died on the 28 January 1547, and went on to marry Sir Thomas Seymour, a man for whom she'd had feelings for before her marriage to the king but passed over because he wasn't the king.
