What common behavioral change might indicate a pet is experiencing health issues?

Changes in appetite or drinking habits can be a significant indicator that a pet is experiencing health issues. Pets that suddenly eat less or more than usual, or that show increased or decreased thirst, may be signaling underlying health problems such as dental issues, infections, or metabolic disorders. These changes can manifest as a direct response to discomfort, pain, or the body's attempt to cope with illness.

In contrast, other options such as playing more frequently, being more social with humans, or showing increased interest in toys are typically associated with positive behavioral changes. While these behaviors may suggest that a pet is happy or adjusting well to their environment, they are less likely to indicate health concerns. Monitoring a pet's appetite and drinking habits is therefore crucial for early detection of potential health issues, making it a vital aspect of responsible pet care.
