Care methods for senior cats:
1. Trim the nails and brush the fur of older cats more often to prevent nails from growing into the flesh.
2. Older cats are more prone to dehydration, so it's important to keep them hydrated. You can feed them wet food to increase their water intake. 
3. Special attention should be paid to the oral care of senior cats to prevent them from losing their teeth prematurely.
4. As the physiological functions of older cats decline, supplementing their diet with appropriate nutrients can help maintain their health.
5. If an older cat has poor digestion and a decreased appetite, it is best to adjust its diet by alternating between dry food and wet food/canned food.
