How to Deworm a Cat?

Deworming a cat includes internal and external treatment; the first session starts at about 45 days old, with both internal and external deworming done monthly before age 1. After age 1, if the cat rarely eats raw meat and lives in clean conditions, internal deworming can be spaced to every 2-3 months, while external deworming is still best done monthly.

For three days before and after applying a topical drop, do not bathe the cat, as this affects the deworming effect.
