Pregnant cats cannot take anthelmintic drugs because most of the ingredients in the anthelmintic drugs currently on the market may cause abnormal development of the fetus during pregnancy, or even death. Therefore, it is recommended to conduct a comprehensive internal and external deworming two months before deciding to breed the cat to prevent the cat from being infected with parasites during pregnancy.

What to do if a pregnant cat accidentally eats anthelmintic drugs:

1. If a pregnant cat accidentally eats anthelmintic drugs, close observation and comprehensive inspection are required.

2. If the anthelmintic drug has a relatively small impact on the fetus in the body, it generally will not affect the normal development of the fetus.

3. If anthelmintics have a greater impact on the fetus, it is generally more likely to cause miscarriage. If abnormalities occur, such as bleeding from the vaginal tract, discharge of abnormal fluid, etc., they need to be taken to a pet hospital for treatment in time.
