My Cat Went Missing Two Weeks Ago And Came Back, I Was Amazed That He Didn't Lose That Much Weigh. How Long Can He Go Without Food And Water? I'm So Glad He's Back,

I doubt that your cat didn't eat a mouse or rat of some sort.

Your cat might have been acquired by another family left and came back to you and they fed him.
