The Puppy and the Dog They have been man’s companion through the ages and adapted to their owners, but they have their own behavioural and nutritional demands. Knowing and respectingthem will guarantee their health and well-being.

The cat’s feline nature is always a matter of fascination.He adapts with apparent ease to daily life, and yet he has behavioural and nutritional requirements of his own. Knowing them and respecting them will guarantee his well-being and his health.

Because of its composition, a Royal Canin Health Nutrition food provides all essential nutrients measured out with utmost precision in order to contribute every day and on a long-term basis to the well-being and health of every animal, according to his age, his size, his physiological condition and his breed.

Innovation for the sake of dogs and cats’ health. For over 40 years, Royal Canin has worked with breeder partners and veterinary nutritionists to go ever further into innovation and precision to enable us to formulate nutritional solutions which perfectly meet dogs and cats’ real needs.




Sodium intake does not pose any particular problems, as cats and dogs do not transpire, even in case of intense physical effort, unlike humans and horses. Only some heart diseases require a reduction in the dietary sodium intake. During severe diarrhoea, hydration powders should be used in the animal’s drinking water.These must be isotonic, to compensate for electrolyte loss, especially sodium.

A little background information

Sodium is a major mineral element, an alkaline metal, that nutritionists call a mineral macro element due to the large amounts needed by the body.

Its role in the body

This mineral element is essential for the cell’s functioning:

  • it maintains the pressure balance between the inside and the outside of the cell;
  • it plays major roles in the cell's energy metabolism.

Sodium is also the element that regulates water balance: sensation of thirst or urinary elimination. Its role is very closely linked to that of potassium. The simplest way to prevent the formation of urinary stones in cats is to encourage the animal to drink and so eliminate the sodium. Major urine volumes increase the frequency of urination and so help evacuate the crystals forming in the urinary tract. Slightly increasing the sodium chloride content in the food encourages the consumption of water and stimulates urine output.

Natural sources

The sodium needed by the animal is provided through sodium chloride (kitchen salt or NaCl), of mineral or marine origin, which contains 39% sodium and 61% chloride. Increasing the NaCl content in a food by 2.5% represents a 1% increase in the sodium content.
