How to give deworming medication to a pet cat? Prepare the dosage of deworming medication prescribed by the veterinarian and give the medication two hours after the cat has finished eating. You can open the corners of the cat's mouth and place the tablet directly into the cat's throat for it to swallow, or mix it into the cat's daily food. For a few days after giving the deworming medication, pay attention to the cat's stool. 
First and foremost, you need to prepare the deworming medication, of course, at the dosage prescribed by your veterinarian. It's important to note that you should minimize gastrointestinal irritation while still ensuring the medication's effectiveness. For example, it's best to give your cat deworming medication two hours after eating. At this time, most of the food in their stomach has been digested, and their digestive system is neither fully empty nor overloaded. This allows the medication to mix better with the food and be digested more effectively. Giving the medication at this time reduces the frequency of vomiting and ensures the medication is more effective at eliminating parasites.
When giving your cat deworming medication, if it's a well-behaved cat, you can gently pry open its mouth, place the tablet down its throat, close its mouth tightly, and hold for 10 seconds to allow it to swallow completely. If that doesn't work, you can mix the tablet into its regular food so it ingests the medication while eating.
It's important to note that for a few days after your cat finishes taking the deworming medication, you should carefully observe its stool. Sometimes, parasite eggs or dead parasites may be expelled along with the stool. If your cat continues to expel parasites, it's best to consult a veterinarian to see if a follow-up treatment is needed or if another deworming medication needs to be given after a period of time.
