To help your cat successfully lose weight, you can refer to the following methods:
1. The most important aspect of weight loss is controlling food intake. Owners should feed their cats at regular times and in fixed quantities, and can feed them smaller meals more frequently, so that the cat eats as little as possible without being hungry, thereby effectively controlling the cat's food intake.

2. Choose cat food that is high in fiber and low in fat. This will ensure your cat gets the necessary nutrition and help them lose weight healthily. However, your cat may experience gastrointestinal upset during the food switch, so you need to carefully observe your cat's reaction.
3. Quitting snacks is also key to weight loss, as snacks often contain high calories, which is not conducive to a cat's weight loss.
