The external deworming medicine for cats dropped on the fur may have a certain effect, but the effect may be affected by some factors.

The external deworming drug is designed to come into contact with the cat's skin so that the drug can be absorbed Absorb and function. If the drug is only dropped on the hair, it may not effectively come into contact with the skin, thus reducing the effectiveness of repelling insects.

If you have any questions about the use or effectiveness of external anthelmintics, it is best to consult a veterinarian or pet health professional who can provide specific advice and guidance. In addition, regular external deworming is one of the important measures to keep cats healthy. At the same time, attention should be paid to the cleanliness and hygiene of the environment to reduce the chance of parasite infection.
