As Terfel, a dog who lives in Wales, aged, his eyes became blurred by cataracts. Eventually he became completely blind. Terfel's owner, Judy Godfrey-Brown, said he had a hard time adjusting; he walked into walls and became afraid to move around the house. When Godfrey-Brown invited a stray cat into her home, it was like the answer to a prayer. The new cat, named Pwditat (this is in Wales, remember) immediately became a guide for Terfel. The cat uses her paws to guide Terfel around the house and into the garden for some fresh air. The two animals became inseparable, and even sleep together.
