Simply put, high protein+low fat+low carbon water+low fiber+enough water.
1, a high-protein and high-protein diet helps fat cats maintain their body muscles, so that they can lose weight without losing muscle, and change from solid fat to puffiness.
Protein is divided into animal protein and plant protein. Cats are carnivores, and animal proteins are easy to digest and absorb, while plant proteins are difficult to absorb. Therefore, when choosing cat food, you must choose cat food with animal protein as the main component, and don't choose cat food with plant protein raw materials such as corn protein, pea protein and rice protein powder.
One thing to note is that the higher the crude protein, the better. Too high will not only soften the stool, but also put pressure on the cat's kidneys. Therefore, generally choose 40-50% crude protein, depending on the adaptability of the cat's stomach.
2. Low fat and low fat are not suitable for all cats who want to lose weight. For example, an old cat needs to choose a medium-fat food to lose weight, because the old cat will be picky about food and eat less. If losing weight is not good for their health, they need some fat to maintain their weight.
For normal fat cats, the crude fat is only 9%- 15%, and the crude fat of about 15% can maintain the normal body shape, but it can also achieve the effect of losing weight by reducing the feeding amount. However, 9% crude fat will make cats thinner, so normal feeding amount is enough.
3, low-carbon water cats have a small amount of amylase, which can help cats digest some starch, so cats can eat a certain amount of carbohydrates, but if it is excessive, it will lead to obesity, malnutrition for a long time, and it will make the stomach fat and limbs thin.
Therefore, whether cats need to lose weight or not, they should choose low-carbon cat food.
Carbohydrate = 100%- protein-fat-moisture-ash.
4. Low-fiber fiber can help the cat's gastrointestinal peristalsis and promote the digestive system, that is, the hair balls are excluded from the body. But too much plant fiber will absorb and swell, and the cat's feces will be full of water, thick and wet. First, it will cause diarrhea and the feces will stink. Second, it will lose water. Third, it will affect the normal absorption of protein.
Therefore, if the crude fiber is less than 5% of dry food, there is no need to add homemade cat rice specially, unless cats with difficulty in defecation need additional plant fiber assistance.
5, moisture problem Because cats don't like to drink too much water, the moisture problem is a very serious problem, otherwise there will not be so many food and water dispensers that cheat water.
You can still choose to use the metabolic energy calculation method: RER (kilocalories per day) = weight kg*30+70.
For example, a cat weighing 15 kg needs 7.5kg*30+70=280kcal, which means that a cat needs 280 ml of water to achieve the ideal drinking water. But the value calculated in this way is too large, so there can be about 20% down.
To sum up, if the slimming cat chooses to eat cat food:
Crude protein 40-50%
Crude fat 9%- 15%
The content of crude fiber is less than 5%
The carbohydrate content is less than 20%
If you choose homemade cat rice, just pay attention to the collocation of ingredients. For example, the proportion of raw meat feeding diet can refer to:
7- 10% skeleton (can replace eggshell powder in the initial stage)
4-5% liver (necessary)
80-85% muscle tissue (including heart and roe deer)
5% other internal organs (brain, waist, pancreas, spleen, unnecessary, best)
