Katy McGaw is one of the pre-made elderly NPC Garden Club members from Weather, the Secret sub-neighborhood that ships with The Sims 2: Seasons. She appears in all neighborhoods, once the Seasons expansion pack has been installed. Katy can be made playable by befriending and asking her to move in, or by marrying her.
She has long grey hair tied back with a yellow clip, green eyes, and light skin. Katy can be recognized by her pink outfit. She also wears lipstick, eye shadow, and blush makeup. Katy is mostly interested in Food, Culture, Money, and Entertainment. She has the same facial structure as Holly Andersen. According to Katy's SimDNA in SimPE, her hair was brown before it turned grey.
Like other garden club members, she will sometimes appear at Community lots. Katy shares her last name with two Sims named Camryn McGaw, a child townie from Strangetown, and a college student from La Fiesta Tech. However, there isn't any evidence that she is related to either of them.
