Although this percentage gives an initial indication of the quality level of the kibble, it cannot indicate on its own the quality level of the food.

The percentage of protein indicated can be compared to the metabolizable energy or number of calories in the food to obtain the RPC or protein-calorie ratio. The latter makes it possible to evaluate the protein concentration of a food in relation to the calories it provides and therefore makes it possible to know the quantity of protein ingested in relation to the energy requirement covered.

For a sterilized cat, for example, we would prefer a low-calorie food with a high crude protein content, and therefore a high RPC as well.

Please note that the RPC is quantitative and not qualitative ! It does not allow the quality of the proteins present in the food to be assessed.

While a high protein level is essential for good health in cats, these proteins must also and above all be of high quality so that they can assimilate them.

“Bad proteins” are not used by the body and are eliminated in the urine. Excessive consumption of this type of food can put excessive strain on the kidneys and eventually lead to chronic kidney disease.

To check this, a few indicators can help you see things more clearly:

* Protein-phosphorus ratio (PPR): qualitative protein sources, or those with high biological value (percentage of protein retained by the body) have a high PPR (greater than 35). These include: fish, meat, eggs and offal.

To calculate it, simply divide the crude protein rate by the phosphorus rate .

* Phosphorus level : The phosphorus level is an indirect indicator of quality. Phosphorus is present in cereals and meat. But it is found most in carcasses, cartilage and fish bones. If the phosphorus level in the food is high, the proteins probably come mainly from carcass rather than meat materials.

Be careful, a low phosphorus indicator is not a guarantee of quality in itself. If the proteins present in the food are of plant origin, the phosphorus level may be low but the protein will still not be of interest to the cat, a strict carnivore by nature.

* Crude Ash Content : The crude ash content indicates the amount of minerals (calcium, phosphorus, magnesium, etc.) present in your cat's food, after complete combustion of the latter. The higher the latter, the more it is suggested that the food contains a significant amount of carcass!

Your cat's body is not adapted to absorb and metabolize too much carbohydrate. If there is an excess of ENA (starch and sugars) compared to energy needs, glucose is stored as glycogen or converted into fat by insulin.

A diet too rich in carbohydrates, in addition to not being well digested by all cats, could therefore have consequences on their health: overweight, obesity, diabetes, etc.

Carbohydrate-free kibble does not exist, because to make kibble you must use starch, which is nothing other than a carbohydrate.

For your cat, pay attention to the carbohydrate level and choose balanced kibble that is low in carbohydrates.

Phosphorus is a micronutrient essential to your cat's health, which is involved in the synthesis of amino acids and proteins. It also allows your whiskered cat's body to absorb calcium.

Phosphorus is therefore essential, but when it is present in too great a quantity, it can conversely damage your cat's kidneys.

The best kibble for your cat is rich in quality animal protein, low in carbohydrates but also low in phosphorus.
This is particularly true for an adult cat, after sterilization or even for a senior cat (+ 8 years) for whom the kidneys may be more sensitive.

It is also important to compare the phosphorus level to the calcium level. In nutrition, balance is key; for a healthy cat, a Ca/P ratio of between 1 and 2 is recommended.

Ziggy kibble contains 44% high quality protein :
- The protein-calorie ratio is 114.97 g/McalEM. ( high ratio, greater than 100 as recommended for sterilized adult cats )
- The protein-phosphoric ratio is 57.14 ( very largely > 35 )
- The rate of raw ash ( minerals ) is 6.5% ( rate lower than market averages )

These elements demonstrate the quality of the animal proteins used in our kibble.

To complement this, we carry out in-depth nutritional analyses on each of our productions, including amino acid analyses (aminograms) that we provide to our partners.

Proteins play a fundamental role for cats, in muscular and visual functions, immunity, reproduction, the nervous system, skin and coat health... Kibble rich in quality proteins as well as a good supply of essential amino acids promote the development and maintenance of muscle mass, a cat in good health and comfortable in its paws!

Carbohydrate-free kibble does not exist, because to make it you necessarily have to use starch. For the health of our little companions, we have reduced the amount of carbohydrates in our kibble as much as possible: count between 18 and 24% depending on the recipes .

A very low-carb, grain-free recipe, made with very high-quality animal proteins and good vegetables, sources of fiber and deliciousness, to promote healthy digestion and less odorous stools .

Ziggy Chicken kibble for sterilized adult cats contains only 0.77% phosphorus, a very low level that helps preserve cats' kidney function.

The calcium to phosphorus ratio of Ziggy kibble is 1.23.

Ziggy kibbles are perfectly balanced and contain real good ingredients: high quality animal proteins, vegetables, sources of fiber, animal and vegetable oils, sources of essential fatty acids and EPA & DHA, vitamins, minerals and trace elements to delight your cat while taking care of him.

They are low in fat but very appetizing, with a fat content of 13.5%.
