# Pet Feeding

Players must regularly purchase and feed their pets to maintain their vitality and health. The game offers a variety of food options, each with specific energy values and costs:

| **Food Type** | **Energy Value** | **Energy Price (XTO)** |
| ------------- | ---------------- | ---------------------- |
| Carrot        | 100              | 10                     |
| Milk          | 200              | 20                     |
| Bread         | 300              | 30                     |
| Fish          | 400              | 40                     |
| Roast Chicken | 500              | 50                     |
| Steak         | 600              | 60                     |

 Players can directly buy food on the "Pet" page, and the system will automatically feed the pets after purchase. Players can buy up to three days’ worth of food at one time. The table below shows the daily energy requirement for pets at different levels:
