Swollen cat feet may be caused by physical injury or poor development. Pay attention to the cat's physical condition. If you find any wounds, you can disinfect them with iodophor first, and then take the cat to the pet hospital for examination and treatment. You should pay attention to it at ordinary times. In the cat’s diet, feed some nutritional paste, goat milk powder, fish and other foods to supplement the cat’s nutrition and promote physical development.
