Hypercalcaemia in Cats
Hypercalcaemic cats are most likely to present with non-specific signs of anorexia and lethargy, although PU/PD, gastrointestinal (GI), urinary and neurological signs are also reported. Accurate assessment of calcium status in cats ideally requires ionised calcium levels to be measured. History is often more valuable than clinical examination in suggesting an underlying cause that can be further evaluated with routine assessment of kidney function, imaging and measurement of parathyroid hormone (PTH), parathyroid-related peptide (PTHrP) and vitamin D levels. Despite extensive investigation, a significant proportion of cats have idiopathic hypercalcaemia.This article briefly reviews the basic physiology and pathophysiology of calcium metabolism before focussing on the clinical approach to the hypercalcaemic cat. This is followed by a discussion of the various recognised causes of hypercalcaemia in the cat and their treatment.
