Pills to Kill Fleas on Cats
After an adult cat flea acquires a host, it will remain there. They are permanent parasites and will only leave the host when they are groomed off, or either the host or flea dies. They rely on constant blood meals to survive and reproduce.
Oral medications for flea control typically contain the active ingredient nitenpyram, an insect neurotoxin. after a cat is given a pill, adult fleas will begin to die within 30 minutes. 90% of the corporeal flea population on the cat will die within 6 hours.
