Understanding chronic kidney failure in animals

Chronic kidney disease (CKD) is a common condition in older dogs and especially in senior cats. It corresponds to a progressive and irreversible decline in kidney function. The kidneys are no longer able to properly filter waste products from the blood (urea, creatinine, phosphorus, etc.), which leads to:

• a loss of appetite,
• excessive thirst (polydipsia) and increased urine production (polyuria),
• weight loss,
• digestive problems (nausea, vomiting),
• general fatigue.

Although CKD cannot be cured, a suitable diet can slow its progression and significantly improve the animal's quality of life.

Why is nutrition essential in the case of CKD?

Diet plays a major therapeutic role in the management of chronic kidney failure:

1. Reduction of the kidney workload

By reducing certain nutrients (excess protein, phosphorus), we limit the production of nitrogenous waste and the progression of the disease.

2. Preservation of nutritional status

A balance must be found: limit protein intake but ensure its biological quality (from good quality meat or fish). The goal is to avoid muscle loss.

3. Control of metabolic imbalances

• Reduced phosphorus : slows the progression of kidney damage.
• Appropriate sodium content : blood pressure control.
• Increased intake of essential fatty acids (omega-3) : anti-inflammatory and kidney-protective effect.

How to feed a dog or cat with kidney failure?

1. Veterinary therapeutic foods

Opt for wet food, but be mindful of the sodium (salt) content. Some holistic veterinarians advise against long-term feeding of wet food. While homemade diets are expensive, they offer a good alternative.

2. Adapted household rations

An alternative is a custom-made homemade ration , prepared using lean meats, digestible vegetables, well-tolerated carbohydrate sources, and supplemented with minerals/vitamins.

3. Promote hydration

For cats, which are lazy drinkers, hydration is a major issue:

• offer wet food (pâtés, homemade rations),
• Opt for distilled water,
• Place several bowls of fresh water,
• use water fountains,
• Add a little warm water to the ration.

Practical tips for everyday life

• Gradual dietary transition : introduce renal food over 10 to 15 days to avoid digestive problems.
• Palatability : gently warm the food or add a little water to release the aromas.
• Regular veterinary monitoring : blood and urine tests to adjust the ration according to the progression of the disease.
• Monitoring weight and muscle mass : adjusting quantities to maintain good overall condition.

Conclusion

Chronic kidney disease in dogs and cats is a serious condition, but a suitable diet can slow its progression and improve the animal's quality of life.
If your pet refuses to eat or is lethargic, consult your veterinarian.
