Hypercalcaemia in cats causes muscle weakness, lethargy, kidney damage, and urinary calculi. Identifying and treating the underlying cause is essential for welfare, as management differs by aetiology.
Hypercalcaemia causes significant suffering through muscle weakness, lethargy, and nausea that reduces quality of life substantially. The welfare management priority is identifying the underlying cause, as this determines both prognosis and treatment approach. Prompt investigation and cause-specific treatment minimises the duration of suffering and prevents the progressive kidney damage that compounds long-term welfare problems.
