Senior cats face a distinct constellation of age-related health conditions that require proactive management to prevent prolonged suffering in what should be comfortable final years.
Senior cat welfare requires vigilance because cats hide illness and pain with exceptional skill — by the time a cat shows obvious signs of disease, significant suffering has often already occurred. Chronic kidney disease, arthritis, and hyperthyroidism all cause progressive suffering that is measurable through bloodwork and examination before it becomes behaviorally obvious. Annual then biannual screening for senior cats provides early detection windows that allow treatment to begin before significant welfare deterioration. The combination of multiple concurrent age-related conditions in elderly cats requires holistic quality of life assessment that considers how treatments for one condition affect others.
