To help cats lose weight successfully, owners can refer to the following methods:

1. The most important part of losing weight is to control food intake. The owner should feed the cat regularly and quantitatively, and can eat small meals frequently so that the cat can eat as little as possible without being hungry, thereby effectively controlling the cat's food intake.

2. Choose cat food with high fiber and low fat content, which can not only ensure the cat's nutrition, but also allow the cat to lose weight healthily. However, during the process of changing food, cats may experience gastrointestinal discomfort, so you need to pay attention to the cat’s reaction when changing food.

3. Giving up snacks is also the key to losing weight. Snacks often contain high calories, which is not conducive to cats losing weight.
