Cells use calcium for sending signals, contracting muscles (including the heart!) and sending / receiving neurotransmitters.

The onset of action is approximately two weeks, with effects persisting for up to several months, so levels may be checked and doses adjusted every 1-3 months. Calcitriol (1,25 dihydroxy vitamin D) does not require hydroxylation in the liver or the kidney, so it is often used in patients with renal failure.

What causes low calcium in cats?

In the cat, chronic renal failure (CRF) (also called chronic kidney disease [CKD]) is the most common cause of hypocalcemia.

What causes elevated calcium in cats?

Causes of Hypercalcemia in Dogs and Cats

In cats, idiopathic hypercalcemia appears to be the most frequent cause of a high total calcium concentration, followed by renal failure and malignancy. Ionized hypercalcemia in conjunction with chronic renal failure is more common in cats than dogs.

What do you feed a cat with hypercalcemia?

Canned foods that are high in protein, low in carbohydrates, and don't contain dl-methionine, phosphoric acid, and ammonium chloride (to avoid acidification) or organ meats and fish oil (rich sources of vitamin D) are suitable for most cats.
