There are two kinds of obesity in cats. One is full body fat, and the other is fat belly and thin limbs, which need to be adapted to different dietary conditions. For example, full body fat is because it eats more fat than protein, and belly fat is because it eats more carbon than protein.

Therefore, when choosing cat food, we should be targeted. 1. Learn to calculate the daily resting calorie requirement of cats, RER (in kcal/ day) = weight kg*3+7.

For example, a fat cat weighing 15kg needs calories every day: 7kg*3+7=28kcal. If it is particularly fat and does not exercise, it can be reduced by 2%-4% on the calculated value.

However, most cat food bags are not marked with calorie value, but this cat food is marked with 43kcal/kg, which means that a fat cat of 15 kg can eat 28/43≈.65kg a day, that is, 65 grams.

There are also feeding suggestions on the bag of this cat food. Cats of 6-7kg can be fed 85g a day to maintain their weight and 57g to lose weight, which is not much different from the food eaten by slimming cats. But when feeding, don't reduce it at once, but reduce it gradually and slowly, so that the cat can adapt. 2. Grain selection criteria: high protein, low fat, low carbon water and low fiber.

Protein is mainly animal protein, and both fat and carbohydrate can make cats fat. Although fiber can increase cats' satiety, it actually hinders the absorption of nutrients. Cats will change from full fat to puffy fat, and their muscles will be gone, and too high fiber may make them soft.

With regard to the choice of main meat in cat food, white meat is the main diet for cats, such as fish, chicken, duck and so on, because white meat has lower calories than red meat. If you choose to make your own, red meat and white meat can be used, but all meat should be controlled in a certain amount. 3. Different production processes make different choices of cat food.

puffed food/dry food

The most popular food in the market is puffed food, and puffed food needs starch to bond, especially the low-fat food, which is basically high protein+low fat+high carbon water+high fiber or low protein+low fat+high carbon water+high fiber.

Therefore, you must look carefully when choosing cat food.

In addition, the calculation method of carbohydrate is: 1%- protein-fat-moisture-ash = carbohydrate.

staple food jar/wet grain

besides puffed grain, staple food jar (wet grain) is also a good choice, which can be mixed with dry grain and wet grain to achieve the goal of ensuring adequate nutrition and losing weight.

for the choice of staple food cans, you can try to choose the one with low fiber and fat content, and then focus on white meat, such as chicken formula. 4. If you want to lose weight, you must eat less and eat more meals, and increase exercise appropriately.

For example, 65g of cat food a day can be divided into five meals, which can also increase the amount of exercise. If it is an old cat or a cat with heart disease, it is not suitable for exercise to lose weight.
