How to deworm a cat? For the health of both the cat and ourselves, cat owners should deworm their cats on time, especially stray cats they have taken in from outside.
1. Types of deworming medications
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 broad-spectrum deworming medications can also be used. However, I believe that although imported deworming medications are more expensive, since cats only need to be treated once a year, it's safer to use imported medications, as deworming medications can be toxic, and improper use can lead to serious consequences. 
2. Dosage of deworming medication for cats
Deworming medication is toxic, so it's crucial to administer it strictly according to the instructions, especially domestically produced deworming medications. Always weigh your cat before administering the medication and calculate the dosage based on their weight. Sometimes you might have a lot of medication left over; if you feel it's wasteful, you can give it to stray cats.
3. Preparations before and after deworming a cat
Before treating a cat for external parasites, bathe it and let it air dry completely. Then apply the parasite medication to the back of the cat's neck where it cannot lick itself. Do not bathe the cat again until the parasite medication has worn off.
When deworming a cat, it should be done 3-4 hours after the cat has eaten. After administering the deworming medication, the cat should not eat for 5-6 hours to ensure the medication is effective.
4. Never use external parasite control products that are added to bath water.
A friend once asked me about external parasite control. I told him to buy Frontline drops, but he couldn't find them. Instead, he bought a type of deworming medication that was added to the bath water for his cat, based on the advice of a pet store clerk. He only consulted me after using it, and I immediately realized that this deworming medication was not safe to use, but it was too late. His cat died from poisoning.
Cats have a unique skin structure, allowing toxic substances to penetrate their bodies through the skin. Combined with their habit of licking their fur, using deworming medication can lead to poisoning and death in cats.
5. Do not use flea collars for external parasite control.
Most flea collars are made with dichlorvos, which is highly toxic and very harmful to cats.
6. After deworming, carefully observe the cat's feces.
A few days after deworming, dead parasites and their eggs will usually be expelled with the stool. If diarrhea occurs, it is best to consult a doctor.
7. After deworming, carefully observe your cat's mental state.
After deworming, some cats with weaker digestive systems or poorer constitutions may experience symptoms such as vomiting, lethargy, or even fever. These symptoms usually improve within 1-2 days. If they persist for several days, it is best to consult a veterinarian.
