Ребят, может я что-то не так вижу, но, по-моему у меня одинаковый вывод строк. Почему валидатор ругается только на третью строчку, никак не могу понять.
Мой вывод:
Cat name is дедушка Вася, no mother, no father
Cat name is бабушка Мурка, no mother, no father
Cat name is папа Котофей, no mather, father is дедушка Вася
Cat name is мама Василиса, mother is бабушка Мурка, no father
Cat name is сын Мурчик, mother is мама Василиса, father is папа Котофей
Cat name is дочь Пушинка, mother is мама Василиса, father is папа Котофей
