When you are pregnant, prolactin changes are completely normal. In fact, your prolactin must increase in order to encourage the production of milk in your mammary glands. During pregnancy your hormones are all over the place. In particular, your estrogen levels begin to rise, and this is what stimulates the increase in your prolactin levels.
Hypercalcemia in Cats. Hypercalcemia is characterized by an abnormally high amount of calcium in the blood. A cat is considered hypercalcemic when its total serum calcium level is greater than 10.5 mg/dL.
Hyperphosphatemia is commonly seen in cats with acute pyelonephritis, acute renal tubular necrosis from a toxic insult (e.g., lily toxicosis), intraluminal trauma from the presence or passage of stones (i.e. ureteral calculi), acute renal failure, chronic renal disease and Conn's syndrome.
