Frequently Asked Questions Frontline Plus for Cats

Q. Do I need a prescription to order? 
A. No. This is an over-the-counter flea & tick product available without any prescription required.


Q. How quickly does FRONTLINE flea and tick protection kill parasites?
A. Research has shown that FRONTLINE for cats will kill 100% of your cat's fleas within 24 hours and kills 100% of your cat's ticks within 48 hours of application.


Q. Do fleas and ticks have to bite my cat for FRONTLINE to work?
A. No. FRONTLINE supplies your cat with protection if fleas simply come into contact with your cat's coat within the post-application time periods mentioned above. 


Q. I just applied FRONTLINE, but I still see active fleas. Why?
A. Fipronil, an active ingredient of FRONTLINE, works by blocking stabilizing ions in the neurons of invertebrates like fleas. Without the stabilizing ions, the fleas die from hyperstimulation. This means that the fleas may become slightly more active just before they die. However, you should rest assure that this is a sign that FRONTLINE is working. 


Q. I treated my cat with FRONTLINE, but I still see fleas in my home. Why?
A. The fleas you see may have hatched from flea eggs that were laid before you began using FRONTLINE for cats. Regular application of FRONTLINE flea and tick protection to your cat will break the flea's life cycle.


Q. How does FRONTLINE kill fleas before they can lay eggs on my cat?
A. An adult flea must be present on your cat for at least 24 to 36 hours before it can lay eggs. Research indicates that FRONTLINE will kill your cat's fleas within 24 hours of application--before the fleas can lay eggs. 

Q. Which FRONTLINE product is right for my cat?

FRONTLINE Top Spot provides fast-acting, long-lasting flea and tick control for cats. Ask your veterinarian which FRONTLINE product is the best choice for your cat. 

Q. Can FRONTLINE be reapplied before the 30-day treatment interval is up?
