After a pet cat eats a cockroach, you should observe whether the cat has any abnormal reactions. If the cat has vomiting, diarrhea, blood in the stool, etc., it is likely to be poisoned, and it is best to send it to a pet hospital for treatment immediately; if the cat within three days If there are no other abnormal reactions, it means everything is fine. You only need to feed the cat appropriate probiotics to regulate the intestines, and remember to deworm the cat at the same time.
