If a kitten has fleas at one month, it should be dewormed. Isolate the cat and use anthelmintic drugs such as DaCaiAi and Fulian to deworm the kitten. Pay attention to strict control of the dosage to avoid poisoning the cat. If the flea problem is serious, it is recommended to take it to the hospital for treatment by a doctor.

Under normal circumstances, preventive deworming for cats is recommended once every three months for external deworming and internal deworming. Therapeutic deworming can be done once a week or two until cure is achieved. Fleas are common external parasites. Their long-term presence may cause allergic dermatitis in cats, and may also deprive cats of nutrients, leading to malnutrition in cats.
