After the cat eats cockroaches, you need to observe the cat's condition first. If the cat has vomiting, diarrhea, poor energy, loss of appetite, etc., it is best to send it to the pet hospital immediately for examination and treatment to avoid poisoning the cat; if the cat has no symptoms after eating cockroaches, If other abnormalities occur, the cat needs to be dewormed on time, because there are more parasite eggs in the cockroach body to prevent the cat from being infected with internal parasites.
