Idiopathic hypercalcemia in cats, often linked to acidifying diets, presents with varied signs. Prednisone effectively resolved hypercalcemia in some affected felines.

Area of Science:

  • Veterinary Medicine
  • Small Animal Internal Medicine
  • Feline Health

Background:

  • Idiopathic hypercalcemia is an increasingly recognized condition in cats.
  • Associations with calcium oxalate urolithiasis and acidifying diets have been noted.

Purpose of the Study:

  • To investigate the laboratory findings, clinical course, and treatment outcomes for idiopathic hypercalcemia in cats.

Main Methods:

  • Retrospective study of 20 cats with idiopathic hypercalcemia.
  • Analysis of clinical signs, laboratory data, dietary history, and treatment responses.

Main Results:

  • Common clinical signs included vomiting, weight loss, and dysuria.
  • Most cats had normal or low parathyroid hormone levels, with no evidence of neoplasia or primary hyperparathyroidism.

  • Urolithiasis was present in 35% of cats; calcium oxalate uroliths in two.
  • Dietary modification and parathyroidectomy were largely ineffective, but prednisone resolved hypercalcemia in 4 cats.

    • Conclusions:

    • Idiopathic hypercalcemia in cats is a complex condition not typically caused by renal failure or common hypercalcemic diseases.
    • Prednisone shows promise as a treatment option for feline idiopathic hypercalcemia.
