It is visible that a lion is old: they have got some white fur on their muzzle and they are skinnier. Wouldn't it be nice to have simmilar art for hungry lions?

For example:
• 60%-69% hunger - a lion is a bit skinnier than othes;
• 70%-79% hunger - even thinner, bones are more visible;
• 80%-89% hunger - very thin, bony;
• 90%-99% hunger - mostly skin and bones.

It would also let you know your lion's hunger without checking the bar.

Suggested by #171993: it could be a payable feature (like cub poses).

It could look a bit like Event Scar: Emaciated.

Decors showing lions to be hungry (like the one above) would still stay as they are, as some players feed their lions regularly and the decors are useful for story purpose.

The biggest disadvantage of this suggestion is the amount of work that would have to be put in it, that's why it could be a paid feature.
