After Terfel, an eight-year-old Labrador retriever in North Wales, developed cataracts, he began to walls and furniture. Soon the once-energetic dog was spending most of his time in his dog bed, unable to find his way around. On a whim, Terfel's owner Judy Godfrey-Brown let a stray cat, whom she named Pwditat (pronounced Puddy-tat), into her home. The feline made a beeline for the blind dog and began using its paws and head to herd Terfel into the garden. Now the unlikely friends sleep together, and Pwditat helps Terfel find his way everywhere.
