Houdini is a feline magician- a lifesaving, feline magician; although her next magic trick- a disappearing act- lasted a bit too long. Even Christmas miracles have a time limit. Exactly a month ago, at 1 a.m., Houdini alerted her sleeping family that the house was ablaze. Her people and their pup escaped to safety, but Houdini vanished. The flames were so fast-moving, her family feared the worst. They presumed their 11-year-old black cat perished in the rubble. This Massapequa house is on a canal.
