Most cats receive the typical daily recommended amount of calcium in a commercial cat food diet. However, according to Jonathan Roberts, BVSC, a remote veterinarian at petkeen.com, there are several conditions that can cause low calcium levels in cats including:

  • Eclampsia (aka "milk fever"): This can occur in lactating cats within the first few days of nursing.
  • Hypoparathyroidism: A metabolic condition characterized by low calcium and high phosphate.
  • Poor nutrition: If your cat is not getting a well-balanced diet from cat food or is suddenly not eating enough (which could point to other health conditions).

"Oral supplementation of calcium may be beneficial in treating the above diseases. Cats require between 0.5 and 1 gram of calcium per day," Roberts says. "Vitamin D should always be included in any calcium supplement to increase calcium absorption in the intestines."

Sean J. Delaney, BS, DVM, MS, DACVIM (Nutrition), founder of Balance It and Board Certified Veterinary Nutritionist, suggests a calcium supplement that is easily digested and absorbed and that can be administered successfully. "Generally this means a calcium salt such as calcium carbonate or calcium citrate that is a powder or powderized from a tablet form and then mixed with food." He also suggests avoiding dicalcium phosphate "as it also introduces phosphorus and can be derived from bone (an antigenicity concern for some cats with food allergies)."

As with any supplement, always check with your veterinarian before giving them to your cat to make sure it's right for their health and dietary needs. Here are a few good options to discuss with your cat's vet:
