A pet's health value is a crucial indicator of its vitality. Through proper feeding and management, players can ensure their pets are in optimal condition, thereby maximizing progress and returns in the game. Factors affecting pet health value include:

* The pet's health value starts at 100% and gradually decreases if not fed.
* Feeding immediately restores health to 100%.
* If a pet is not fed for over seven days, it will die.
* The health value of a pet also affects the production efficiency of factories.
