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.
High levels of calcium ions (hypercalcemia) occur at free calcium ion concentrations over 5.2 mg/dL or total serum calcium above 10.4 mg/dL. Hypercalcemia usually occurs when the body dissolves bone at an abnormally fast rate, increasing both serum calcium and serum phosphate.
