The sum is a reflection of just how important Arcturus and Cygnus, as well as their brother Sirius and a temporary feline houseguest named Yuki, are to Will and Lauren Powers, according to Will Powers' sister, Brittney Powers. When he woke Sunday morning to find their Farmington Hills home ablaze, Will Powers, 32, frantically searched for the cats but could not locate them before firefighters pulled him out, she said. He left several doors open in hopes the cats would escape, but search parties and live traps placed in the nearby woods have turned up no sign of them, she said.
