What symptoms would alert me if my cat's calcium levels are too high?

High calcium is not very commonly found in cats on well-balanced cat foods. Potential causes for hypercalcemia in cats include lab error or lipemic blood sample, cancer, kidney failure, bone disease, hyperthyroidism, toxic exposure, supplements, among a few others. I would recommend that you follow-up with your vet about these possible concerns. The vet may recommend additional testing, including an ionized Calcium level, which more accurately evaluates the calcium in the body than total calcium on most in-house blood panels.

Unfortunately high calcium levels often do point to a cancerous condition such as lymphoma. And cats are particularly prone to lymphoma. Here is some good information on feline lymphona: http://download.skyscape.com/download/ota/5mvetcf5/documents/pdf/lymphoma-cats.pdf And here is information on hyperparathyroidism: http://download.skyscape.com/download/ota/5mvetcf5/documents/pdf/hyperparathyroidism.pdf If you have any specific question feel free to ask. Sometimes high calcium levels may be idiopathic, ie the cause is unknown. Your vet likely will also send blood in for ionized calcium which will help determine the cause.

According to the PetHealth network, testing involves: Complete blood count to look at the white and red blood cells and platelets Chemistry panel to look at the kidney and liver function Electrolytes to look at the calcium, phosphorous, and salt balance (e.g., sodium, potassium, etc.) Urinalysis to look for the presence of an underlying infection, crystals, or appropriate urine concentration Urine culture to rule out an underlying urinary tract infection Feline leukemia (FELV) and feline immunodeficiency virus (FIV) X-rays to rule out underlying cancer, bladder stones, or evidence of mineralization of tissue (secondary to hypercalcemia) Ultrasound to rule out underlying cancer, bladder stones, or inappropriate mineralization Parathyroid hormone (PTH) and PTH-rP concentration (parathyroid hormone related protein) levels. With hyperparathyroidism, the PTH levels are typically normal to high. With hypercalcemia of malignancy, PTH-rP concentrations are typically elevated. With idiopathic hypercalcemia in cats, PTH levels and PTH-rP levels are typically low. This can be expensive, but necessary to get to the cause. I would speak to Sammy's vet to discuss what tests should be done first. Best of luck.

Hi there. Hyperthyroidism can cause symptoms like increased vocalization and irritability, weight loss, increased appetite, vomiting or diarrhea, and/or increased drinking and urination. It also contributes to high blood pressure, and is hard on the heart and kidneys long-term. If Midnite's thyroid levels are high, treatment would generally be recommended to address this.

Thank you for submitting your question regarding Mylie. Elevated calcium does happen with certain types of cancers. However, it can also be related to kidney failure, certain toxicities, or even a lab error. Typically additional testing is required to determine the cause of high calcium. I hope this information helps!

Hi there. Symptoms of hyperthyroidism generally include things like weight loss, vomiting, diarrhea, excessive vocalization, and increased appetite or thirst. I would tend to agree with your veterinarian that if your kitty is not losing weight or having any other symptoms of a problem, there is no reason to change his medication dosage - although an increase may be needed in the future if he starts to have symptoms again.

Hi and thanks for your request. Neoplasia, chronic renal failure (CRF), and idiopathic hypercalcemia are common causes of elevation of Calcium levels. The approach to this problem with elevated Ca++ I would recommend is: - repeat the blood test and analyze the ionised Ca++ (which can give you a reliable information about the calcium levels). At the same time I would recommend to perform a urine analysis and determine the SDMA value on the blood which can be an early indicator of renal failure; - If then this is a true elevation (Ionised Ca++ elevated) I would recommend to perform x rays of the chest and an abdominal ultrasound. This is to rule out any possibility of a tumor, especially lymphoma which is a common reason for this problem. - Based on these results you can then either treat appropriately or look for other uncommon causes like Hyperparathyroidsm (HP), Vitamin D toxicosis, granulomatous diseases such as Actinomycosis and Criptococcosis, and Hypoadrenocorticism. Regarding the ear discharge, these are typical signs of an infection and antibiotics ear drops are often resolutive.
