It is best to perform internal and external deworming three days after taking a bath, because the skin surface of a cat that has just taken a bath will be more fragile. If you use an external repellent immediately and drop it on the skin surface, the effect will not be that good, and it will not be good for the cat’s skin. ​​​​​​

Secondly, try to keep the cat's internal and external deworming in a healthy state. If he catches a cold the next day after taking a bath, do not carry out internal and external deworming for the time being. It is found that the cat is healthy three days after taking a bath. This is a very good time to deworm.
