Veterinary guidance emphasizes the importance of monitoring subtle behavioral and physical changes in pets to ensure early diagnosis and manage medical costs.

Initial reports highlight that cats often hide signs of illness, such as lethargy, weight loss, or changes in appetite, which can lead to worsened health outcomes and high veterinary expenses. For example, one instance noted a delay in treatment resulted in a bill of 640 euros.

Experts further specify that identifying pain in both dogs and cats is difficult because early symptoms can be mistaken for routine personality traits. Veterinary professor Ana Elisa Arruda Rocha suggests monitoring posture, movement, and facial expressions. Owners are advised to watch for signs like isolation, sudden aggression, anxiety, or unusual vocalizations, which may indicate physical ailments or emotional issues such as stress.
