Feeding Cats With Primary Hyperparathyroidism: Diet Plan

1) Should I put my cat on a low-calcium diet?

Not without veterinary guidance. PHPT requires medical diagnosis and treatment planning, and overly restricting calcium can create new problems. Most cats do best with a consistent complete-and-balanced diet while your vet manages the underlying condition and monitors calcium trends.

2) Is wet food better than dry food for PHPT?

Wet food is often helpful because it increases water intake, which supports hydration and urinary health—both relevant when calcium is high. Some cats do fine with a mix, but many benefit from mostly wet food unless your vet recommends a specific prescription diet format.

3) Can I feed homemade food to control minerals more precisely?

Only if the recipe is formulated for your cat by a board-certified veterinary nutritionist. “DIY” homemade diets frequently have incorrect calcium, phosphorus, and vitamin D levels, which is risky for cats with calcium regulation disorders.

4) Are calcium-rich treats (cheese, yogurt) safe?

Small tastes may not be dangerous for every cat, but regular dairy treats add variable calcium and may cause diarrhea in lactose-sensitive cats. For PHPT support, choose meat-based treats in small amounts and keep treats under 10% of daily calories.

5) What should I do if my cat stops eating during diet changes?

Stop the transition and contact your veterinarian promptly. Cats can develop hepatic lipidosis (fatty liver) if they don’t eat enough, especially if overweight. Your vet can address nausea, pain, constipation, or appetite issues and recommend a safer feeding plan.

6) After surgery, can my cat’s calcium become too low?

Yes. Post-operative hypocalcemia can occur and may require prescribed calcium and/or vitamin D. Follow your veterinarian’s recheck schedule closely and watch for signs such as tremors, twitching, restlessness, weakness, or seizures—seek urgent veterinary care if these occur.

Partner with your veterinarian for individualized diet choices, lab monitoring, and treatment decisions. A thoughtful, moisture-forward, complete-and-balanced diet is a strong foundation while the medical cause of PHPT is addressed.
