Weight loss methods for cats:
1. Snacks are very high in calories, so you should reduce the amount of snacks you give your cat and try not to give them snacks for no reason.
2. You can switch from regular cat food to weight-loss cat food. Weight-loss cat food contains more fiber and less fat, which can prevent your cat from consuming too many calories. 
3. Feed your cat small amounts frequently. This helps with digestion and prevents your cat from accumulating fat.
4. Increase your cat's playtime each day by spending more time playing with it or taking it for walks to burn calories.
5. Owners can also take their cats to a veterinary hospital for a comprehensive physical examination to see if there are any hidden factors contributing to obesity, and let the veterinarian develop a scientific weight loss plan for the cat.
