Machine learning models now detect subtle shifts in posture or sleep that precede visible lameness or cognitive decline.

An 18-year-old cat begins yowling at 3 AM. The owner assumes senility. The behavioral veterinary exam reveals hypertension (high blood pressure) causing blindness and disorientation, coupled with hyperthyroidism causing restlessness. Methimazole and amlodipine stop the yowling in 48 hours.

Sudden behavioral changes in mature animals are often "red flags" for underlying medical issues, such as pain or cognitive decline.
