Garfield cats can be dewormed starting at 4 weeks of age, then again at 8 and 12 weeks. After 12 weeks of age, deworming should be done every 3 months. Deworming helps prevent parasites from interfering with a kitten's growth and development and prevents parasitic enteritis. Of course, regardless of whether the kitten has parasites, pet cats should be dewormed regularly to ensure the health of both the cat and the family. 
Deworming medications for cats are generally divided into internal and external deworming medications. Commonly used internal deworming medications for cats include Milbemax, Bayer, and Advantage. A common external deworming medication for cats is Frontline. All of these are imported deworming medications, although domestically produced ones can also be used. While imported deworming medications are more expensive, cats only need to be treated once a year, so using imported medications is more reliable. As the saying goes, all medicines have some degree of toxicity; improper use can lead to serious consequences.
Deworming medication is toxic, so it is essential to administer it according to the instructions. This is especially important for domestically produced deworming medications. Before administering any medication, be sure to weigh your cat and calculate the appropriate dosage based on their weight.
If your cat experiences diarrhea or vomiting during deworming, don't panic. Cats have delicate digestive systems, and deworming medication can be quite irritating, causing discomfort and vomiting. You can give your cat probiotics after deworming to alleviate the medication's irritation and stop the vomiting and diarrhea. If the symptoms persist, take your cat to the vet immediately.
