During pregnancy, it is not recommended to use internal and external deworming drugs for cats. Since certain drug components in internal and external deworming drugs may cause dysplasia and deformity during pregnancy, it is recommended that cats undergo internal and external deworming once every two months before pregnancy to avoid cats from being infected with parasites during pregnancy. Most of the antiperspirants are inadequately toxic, which can cause gastrointestinal discomfort at the mildest, and can lead to fetal miscarriage at the worst. Therefore, it is recommended that cats take oral anti-worming medicine one week before breeding, which can not only improve their own deworming effect, but also give the fetus good antibodies.
If the cat accidentally takes deworming medicine, be sure to take it to the pet hospital for a detailed examination to prevent problems.
