Cats can be dewormed internally and externally at the same time. Internal deworming and external deworming have no influence on each other, but you should take a bath in advance before deworming, because you cannot take a bath within three days after external deworming. However, deworming should be separated from vaccination to avoid affecting the effectiveness of the medicine.

1. Feed deworming medicine according to the instructions of the deworming medicine and the weight of the cat, usually after eating Feed after 2 hours. Avoid drug dosage that is not up to standard, resulting in poor deworming effect, or drug dosage that is too high, causing poisoning in cats.

2. Generally, cats need to be dewormed once every three months to six months after they become adults. They need to be dewormed once a month before becoming adults.

3. If worms come out after taking oral medicine, it is recommended to deworm once every half month, three times in a row or regularly according to the product you choose.
