FRONTLINE Plus Flea & Tick Treatment for Cats Over 1.5 lbs — 6 Treatments

Overview and benefits

FRONTLINE Plus for Cats is a long-lasting, fast-acting topical treatment designed for cats and kittens eight weeks and older, weighing 1.5 pounds or more. It uses two active ingredients, fipronil and (S)-methoprene, to target adult fleas, flea eggs, flea larvae, chewing lice, and ticks. A single monthly application aims to provide protection for roughly 30 days, helping you maintain a steady routine without frequent reapplications.

How it works and what to expect

The formula is designed to kill fleas at multiple life stages—adult, eggs, and larvae—while also addressing chewing lice and various ticks. It is waterproof, so exposure to moisture doesn’t easily wash away protection, which can be helpful for cats that groom themselves after baths or during wet weather. While results can vary, many pet owners value the ease of a monthly, spot-on treatment that fits into daily life.

• Waterproof protection that remains effective after baths or rain
• Kills adult fleas and disrupts the flea life cycle by also destroying eggs and larvae
• Targets ticks that may transmit Lyme disease, contributing to ongoing protection
• Monthly dose provides a simple, predictable schedule for pet care
• Trusted by pet owners for over 20 years

Who can use it and when

This product is suitable for cats eight weeks and older weighing 1.5 pounds or more. The six-treatment supply offers a convenient, repeatable plan for monthly protection across several weeks, making it easier to stay on track with your cat’s flea and tick protection.

Practical, real-life scenarios

In real life, a quick application at the back of the neck can set the tone for a month of comfort. For households with multiple pets, a consistent monthly routine helps reduce the chance of fleas and ticks moving between animals or entering the home. Whether your cat spends time outdoors, enjoys a sunlit windowsill, or shares spaces with other pets, regular protection can be a helpful part of daily care.

• Waterproof, long-lasting protection that fits busy schedules
• Effective across a range of environments—indoors, outdoors, or hybrid living
• Six treatments in the box support a year-round approach to flea and tick control
