Who is the richest cat in the world list?

Could you please elaborate on the intriguing question of who holds the title of the richest cat in the world? Is this a reference to a feline who has been fortunate enough to inherit a significant fortune, or perhaps one that has become famous through some form of feline entrepreneurship? And furthermore, is there an official list that ranks these feline millionaires, and if so, what criteria are used to determine their wealth and ranking? I'm eager to learn more about this fascinating topic and the feline personalities behind it.
