RESOLUTION OF METASTATIC CALCIFICATION IN THE PAWS OF A CAT WITH SUCCESSFUL DIETARY-MANAGEMENT OF RENAL HYPERPARATHYROIDISM

A 10-year-old ovariohysterectomised domestic shorthaired cat was prese nted with multiple nodular calcifications of the footpads and interdig ital spaces. Renal insufficiency was diagnosed by routine biochemistry and urinalysis. Additionally, the cat had a calcium and phosphorus so lubility product greater than 70 mg/dl and elevated circulating parath yroid hormone. Dietary management of the renal disease resulted in a r eduction in the mineral solubility product and normalisation of the co ncentration of parathyroid hormone accompanied by concurrent resolutio n of the pedal lesions.
