The cat will ask you to give it any year. Then, it will detect if it is a leap year or not. Years that are multiples of 4 (like 2024, 2028, and 2032) are leap years. Multiples of 100 that are multiples of 400 too (like 1600, 2000, and 2400) will also be leap years. Otherwise, they will be common years.
