Hmmm..K.A. don't know about Sim's but I can tell you without a doubt that Cody is shedding up a storm in chunks. We have dry heat so when the heat's on, dust and hair go-a-flying and the Electrolux keep on runnun and runnin! I know Cody needs a good bath but I brush him almost everyday and figured out I can probably knit a doghair sweater!
