After a cat weighing more than 3 pounds takes an entire pill of anthelmintic medicine, its health should be closely monitored. Check whether the cat has any abnormal symptoms, such as vomiting, diarrhea, neurological symptoms, etc. If there are no obvious abnormalities, don't worry about it and just feed it normally.

If the cat has gastrointestinal discomfort, such as diarrhea, vomiting, etc. In this case, timely medical treatment is required. At this time, the cat is more dangerous.
