1. Selection of deworming medication for kittens
For deworming kittens, you can choose medications containing ingredients such as selamectin, fipronil, milbemex, or praziquantel. These medications can effectively prevent or treat intestinal parasites such as tapeworms, roundworms, and hookworms.
2. Frequency and Importance of Deworming
To reduce the risk of parasitic diseases in cats, it is recommended to deworm them internally and externally every 1 to 2 months. The frequency of deworming should be adjusted according to the cat's actual situation, including its living environment and degree of contact with the outside world. 
3. Classification of internal deworming medications
Preventative deworming aims to prevent infection by intestinal parasites such as tapeworms, roundworms, and hookworms. Commonly used medications include fenbendazole, milbemoxime, and praziquantel. Therapeutic deworming is administered when a cat is already infected with parasites.
4. Treatment of specific parasitic infections
In cases of Giardia lamblia infection, kittens may present with diarrhea, producing grayish stools containing mucus and blood; adult cats may only excrete more foamy, pasty stools, with no significant changes in body temperature or appetite. Treatment for this type of infection typically recommends the use of metronidazole or similar medications.
5. The Importance of External Parasite Control
External parasite control is equally important. Medications containing ingredients such as selamectin or fipronil can be used. These medications should be applied to areas that are difficult for the cat to reach, such as the head or neck. The effects of external parasite medications typically last about 30 days, so it is recommended to perform external parasite control every 1 to 2 months.
