How is the health of your individual cubs represented in Shelter?

Solution 1:

There is a visual representation of the health of the individual cubs in Shelter, and it's done through the tint of the cub's color. A "well fed" cub has a colored coat that is almost the same as the mother badger. As time goes on, the color of the cub's coat will start to lighten towards the color of the dying cub from the beginning cave-sequence of the game if the cub has not been fed recently.
