If your cat has been diagnosed with chronic kidney disease (CKD), you may have been advised to switch to a low protein diet. It is true that protein metabolism produces uremic toxins and nitrogenous waste that can burden the kidneys. But when protein is restricted too much, unexpected health problems may arise.
At Greycoat Research, we want to share why balance, not extreme restriction, is the key to safe kidney care.
Four Risks of Excessive Protein Restriction
1. Cardiac Hypertrophy
Without enough protein, the heart muscle loses essential amino acids and becomes weaker. Over time, it may thicken abnormally, raising the risk of heart failure.
2. Arrhythmia and Hypotension
Low protein lowers albumin and reduces muscle mass, disturbing fluid and electrolyte balance. These changes can trigger irregular heartbeats, low blood pressure, or even shock.
3. Kidney Damage
Too little protein weakens the immune system and raises inflammation in the body. This additional stress can accelerate kidney decline rather than protecting kidney function.
4. Worsened Anemia
Protein is essential for producing hemoglobin and red blood cells. Restriction can worsen anemia, leading to fatigue, pale gums, and weakness.
Why Balance Matters
Veterinary-prescribed renal diets are generally safe. However, outside of these carefully formulated diets, any attempt to further restrict protein without consulting a veterinarian or veterinary nutritionist should be approached with caution.
👉 The answer is not “low protein at all costs.” CKD cats need balanced and carefully adjusted protein intake for safe long-term management.
A Message for Cat Guardians
Supporting a CKD cat requires three essentials:
- A balanced low protein diet
- Consistent daily care
-
Evidence-based supplements
Greycoat Research supplements are designed to support AIM activation, cellular health, and toxin reduction. With these three pillars, you can give your cat stronger support for long-term kidney health.
Kidney care is not just about restriction. It is about balance, resilience, and support. Greycoat Research is here to stand with you and your cat every step of the way.
