Feeding Cats With Addison's Disease: Sodium Supplementation

1) Can diet cure Addison’s disease in cats?

No. Addison’s is a hormonal disorder that typically requires lifelong medication. Diet can support hydration and provide consistent mineral intake, but it cannot replace mineralocorticoid and/or glucocorticoid therapy. Work with your veterinarian for a complete treatment plan.

2) Should I switch to a high-sodium cat food?

Not automatically. Many cats do well on a standard complete and balanced diet once medications are correctly dosed. A “higher sodium” approach may be appropriate for documented hyponatremia, but only under veterinary guidance and with follow-up bloodwork.

3) Is it safe to add table salt to my cat’s food?

Only if your veterinarian specifically instructs you to do so and provides a dose. Guessing can cause dangerous sodium shifts, worsen blood pressure, or complicate kidney/heart disease. Never use garlic salt, onion salt, seasoning blends, or salty human foods.

4) What treats are safest for cats with Addison’s disease?

Choose simple, cat-appropriate treats with minimal ingredients and avoid high-sodium processed meats. Better options often include small portions of the cat’s regular food or veterinarian-approved treats. If sodium supplementation is part of the plan, your vet may want treat intake to stay consistent so total sodium doesn’t fluctuate.

5) How will I know if sodium supplementation is helping?

Improvement should be assessed through recheck electrolytes (sodium, potassium, chloride), blood pressure, hydration status, and clinical signs like appetite and energy. Home observations are useful, but lab monitoring is the decision-maker.

6) Are “electrolyte supplements” marketed for pets a good idea?

Use only products your veterinarian recommends. Some over-the-counter electrolyte powders or drops can provide inappropriate sodium/potassium ratios or added ingredients that don’t match your cat’s medical needs. Addison’s management requires precision.

Best next step: If your cat has Addison’s disease (or is being tested for it), bring your cat’s current food label and supplement list to your veterinarian and ask for a sodium plan tied to lab monitoring.
