Here are some solutions for fleas on cats:
Grooming and bathing: Regularly brush your cat's fur with a very fine-toothed comb, working from head to tail and from top to bottom. If you find fleas, kill them immediately. Use flea-repellent shampoo and increase the frequency of bathing as needed.
Medication: Flea collars, sprays and drops for exfoliating parasites can all play a certain role in prevention, but they must be used according to the instructions, otherwise the effectiveness of the medication will be limited.
Feed your cat nutritious food: You can feed your cat some food rich in vitamin E and unsaturated fatty acids. These foods are known as nutrients for cat skin, which can enhance the skin's resistance and relieve itching caused by flea bites.
Clean the environment: Tidy up the home environment, regularly sun-dry textiles, clean up food, skin, and other debris in corners, and spray disinfectants that fleas dislike widely throughout the home.
