Hypercalcemia occurs when a cat\u2019s calcium levels exceed the normal range of approximately 8.5 to 11.0 mg\/dL. Persistent hypercalcemia can affect multiple organ systems, leading to kidney damage, cardiovascular issues, and neurological problems. The condition can be either primary or secondary to an underlying disease.<\/p>\n

Causes of Hypercalcemia in Cats<\/strong><\/h3>\nHypercalcemia in cats can arise from various medical conditions, including:<\/p>\n
\n- Idiopathic Hypercalcemia<\/strong><\/a><\/span> \u2013 The most common cause of hypercalcemia in cats, particularly in middle-aged and older felines. The exact cause remains unknown.<\/li>\n
- Chronic Kidney Disease (CKD)<\/strong> \u2013 Impaired kidney function can disrupt calcium and phosphorus balance, leading to hypercalcemia.<\/li>\n
- Cancer (Neoplasia)<\/strong> \u2013 Lymphoma, squamous cell carcinoma, and other malignancies can lead to elevated calcium levels.<\/li>\n
- Primary Hyperparathyroidism<\/strong> \u2013 A rare condition where the parathyroid glands produce excessive parathyroid hormone (PTH), increasing calcium absorption.<\/li>\n
- Vitamin D Toxicity<\/strong> \u2013 Ingestion of excessive vitamin D supplements, rodenticides, or certain human medications can cause dangerously high calcium levels.<\/li>\n
- Granulomatous Diseases<\/strong> \u2013 Infections or inflammatory conditions, such as fungal infections, can contribute to calcium imbalances.<\/li>\n
- Addison\u2019s Disease<\/strong> \u2013 Hypoadrenocorticism, a disorder of the adrenal glands, can be associated with hypercalcemia.<\/li>\n<\/ol>\n
Symptoms of Hypercalcemia in Cats<\/strong><\/h3>\nThe clinical signs of hypercalcemia vary depending on the severity and underlying cause. Common symptoms include:<\/p>\n
\n- Increased thirst (polydipsia) and urination (polyuria)<\/li>\n
- Lethargy and weakness<\/li>\n
- Decreased appetite (anorexia)<\/li>\n
- Vomiting<\/li>\n
- Constipation<\/li>\n
- Weight loss<\/li>\n
- Muscle tremors or twitching<\/li>\n
- Depression or behavioral changes<\/a><\/span><\/li>\n
- Increased risk of bladder stones due to excess calcium<\/li>\n<\/ul>\n
Additional and Clinical Signs Of Hypercalcemia In Cats<\/strong><\/h3>\nThe clinical signs of hypercalcemia depend on both its severity<\/strong> and the underlying cause<\/strong>. They may be subtle at first but become more pronounced as calcium levels rise:<\/p>\nUrinary & Renal Signs<\/strong><\/p>\n\n- \n
Increased thirst (polydipsia<\/strong>)<\/p>\n<\/li>\n- \n
Increased urination (polyuria<\/strong>)<\/p>\n<\/li>\n- \n
Blood in urine (hematuria<\/strong>) from bladder or kidney irritation<\/p>\n<\/li>\n- \n
Formation of calcium oxalate bladder or kidney stones<\/strong> (uroliths)<\/p>\n<\/li>\n- \n
Possible urinary tract infections due to stones<\/p>\n<\/li>\n<\/ul>\n
Gastrointestinal Signs<\/strong><\/p>\n\n- \n
Reduced appetite (anorexia<\/strong>)<\/p>\n<\/li>\n- \n
Nausea and drooling<\/p>\n<\/li>\n
- \n
Vomiting (sometimes chronic, sometimes intermittent)<\/p>\n<\/li>\n
- \n
Constipation<\/p>\n<\/li>\n
- \n
Abdominal discomfort<\/p>\n<\/li>\n<\/ul>\n
Musculoskeletal & Neurological Signs<\/strong><\/p>\n\n- \n
Muscle weakness or reluctance to jump\/climb<\/p>\n<\/li>\n
- \n
Muscle tremors, twitching, or stiffness<\/p>\n<\/li>\n
- \n
Ataxia (wobbly gait)<\/p>\n<\/li>\n
- \n
Seizures (in severe cases)<\/p>\n<\/li>\n
- \n
Generalized lethargy or depression<\/p>\n<\/li>\n<\/ul>\n
Behavioral & General Signs<\/strong><\/p>\n\n- \n
Irritability or personality changes<\/p>\n<\/li>\n
- \n
Decreased grooming behavior<\/p>\n<\/li>\n
- \n
Weight loss and poor body condition over time<\/p>\n<\/li>\n<\/ul>\n
Cardiovascular Signs<\/strong> (with severe or prolonged hypercalcemia)<\/p>\n\n- \n
High blood pressure (hypertension<\/strong>)<\/p>\n<\/li>\n- \n
Irregular heartbeat (arrhythmias<\/strong>)<\/p>\n<\/li>\n- \n
Collapse in extreme cases<\/p>\n<\/li>\n<\/ul>\n
\u26a0\ufe0f Because these symptoms overlap with kidney disease, hyperthyroidism, cancer, and other feline conditions, blood tests and urinalysis are required for diagnosis<\/strong>. Hypercalcemia should always be evaluated by a veterinarian to determine the underlying cause.<\/p>\nDiagnosing Hypercalcemia in Cats<\/strong><\/h3>\nVeterinarians diagnose hypercalcemia through a combination of physical examination, blood tests, and diagnostic imaging. The following steps are typically involved:<\/p>\n
\n- Blood Tests<\/strong> \u2013 A serum biochemistry panel measures total and ionized calcium levels, as well as kidney function and phosphorus levels.<\/li>\n
- Parathyroid Hormone (PTH) Test<\/strong> \u2013 Determines if hyperparathyroidism is the cause.<\/li>\n
- Vitamin D Testing<\/strong> \u2013 Identifies vitamin D toxicity.<\/li>\n
- Urinalysis<\/strong> \u2013 Checks for kidney function abnormalities or urinary stones.<\/li>\n
- Imaging (X-rays, Ultrasound)<\/strong> \u2013 Detects tumors, kidney disease, or bladder stones.<\/li>\n
- Bone Marrow Aspirate or Biopsy<\/strong> \u2013 In cases where lymphoma or other cancers are suspected.<\/li>\n<\/ol>\n

Treatment Options for Hypercalcemia in Cats<\/strong><\/h3>\nTreatment depends on the severity of hypercalcemia and its underlying cause. The primary goal is to reduce calcium levels while addressing the root issue.<\/p>\n
1. Fluid Therapy<\/strong><\/h4>\nIntravenous (IV) fluid therapy is often the first line of treatment. Increasing fluid intake helps flush excess calcium from the bloodstream through the kidneys.<\/p>\n
2. Dietary Management<\/strong><\/h4>\nA low-calcium, phosphorus-controlled diet may help manage chronic hypercalcemia, particularly in cats with idiopathic hypercalcemia or CKD.<\/p>\n
3. Medications<\/strong><\/h4>\nDepending on the cause, different medications may be used:<\/p>\n
\n- Bisphosphonates<\/strong> (e.g., alendronate) help reduce bone resorption and lower calcium levels.<\/li>\n
- Steroids<\/strong> (e.g., prednisone) may be prescribed for inflammatory or immune-mediated causes.<\/li>\n
- Diuretics<\/strong> (e.g., furosemide) help increase calcium excretion through urine.<\/li>\n
- Calcitonin<\/strong> can be used in severe cases to lower calcium levels temporarily.<\/li>\n<\/ul>\n
4. Treating Underlying Conditions<\/strong><\/h4>\n\n- Surgical Removal of Parathyroid Tumors<\/strong> \u2013 In cases of hyperparathyroidism, surgery may resolve hypercalcemia.<\/li>\n
- Cancer Treatment<\/strong> \u2013 Chemotherapy, radiation, or surgical removal of tumors can help control calcium levels.<\/li>\n
- Infection Management<\/strong> \u2013 If granulomatous disease is the cause, antifungal or antibiotic treatment may be necessary.<\/li>\n<\/ul>\n
\u201cHypercalcemia in dogs and cats. This usually indicates an underlying disease process causing the dysregulation of calcium homeostasis; clinical signs may or may not be evident.\u201d – Kathleen Ham, DVM, MS (Merck Veterinary Manual)<\/a><\/span><\/p>\nPrognosis and Long-Term Management<\/strong><\/h3>\nThe prognosis for hypercalcemia depends on the underlying cause and how quickly treatment is initiated. Cats with idiopathic hypercalcemia can often be managed with dietary changes and medications. However, conditions like lymphoma or advanced kidney disease may have a more guarded prognosis.<\/p>\n
Regular veterinary check-ups, blood work, and monitoring calcium levels are essential for long-term management. In some cases, lifelong treatment is required to prevent complications.<\/p>\n
