To remove parasites from a cat, you first need to identify the type of parasite, as different parasites require different treatment methods. For external parasites, such as fleas and ticks, you can use external deworming agents, such as drops or sprays, applied directly to the cat's skin. For internal parasites, such as roundworms, hookworms, and tapeworms, oral deworming medication is required.

In addition, regularly checking and cleaning your cat's living environment, such as the litter box and cat bed, is also an important measure to prevent parasite infections. At the same time, maintaining good hygiene in your cat's diet and avoiding feeding them raw meat that may contain parasites can also effectively reduce the risk of parasite infection.
