Kitten Mudslide

An old man who lives alone always puts food on the window sill to feed stray cats. One day, he finds that one of the lame white cats has half a yellowed photo in his mouth - it is the childhood photo of his son who has been missing for ten years. He frantically followed the cats to the abandoned factory and found the diary left by his son in the cat's nest: "Dad, the driver responsible for the accident is your subordinate, and the evidence is hidden in the cat's collar." When the police arrested him, the old man hugged the white cat tightly and cried bitterly - the cat's right eye had a heterochromatic iris, exactly the same as his son's.
