I was taking care of a cat owned by a cancer patient who couldn't care for them during their treatments. During that time, we had a real bad ice storm and the cat got out and ran away. This was her favorite cat and she was obviously upset because he stood no chance in the freezing weather . 3 months later when she opened her front door, the lost kitty was sitting on her front porch! Guess the kitty missed its mommy and made the 20 mile trek back to her house. The cat's safety MMD!
