A cat who alerts his deaf owner to visitors and phone calls is in the running for a national award. Zebby, a two-year-old black-and-white cat from Chesterfield, in Derbyshire, taps his owner Genevieve Moss’s face to alert her to put on her hearing aid. Ms. Moss said: “Without my hearing aid, I can’t hear anything, but now I have Zebby to help me.”
