No Pill. Less stress for you and your cat.
Let’s face it. Interrupting your cat’s nap to give medicine isn’t much fun – especially when that medicine is in pill form. In a survey of over 600 cat owners, more than 85% agreed they prefer a topical product to a pill or tablet.1
Painful flea bites are just part of the story.
The truth is, it doesn’t take long for a few fleas to turn into an infestation – even for indoor cats. In one day, a single female flea can lay up to 50 eggs.2 That means it’s easy for one flea to turn into an infestation, which can cause bites that are itchy, uncomfortable, and even painful to your cat.

Advantage Multi® for Cats offers broad-spectrum protection.
-
In addition to killing fleas and treating and controlling ear mites, Advantage Multi® for Cats also treats and controls roundworms and hookworms, and prevents heartworm disease in cats. This broad-spectrum protection is critically important to your cat’s health because:
- Heartworm disease can pose serious health risks for cats, like respiratory disease and even sudden death. Even indoor-only cats are at risk for heartworm disease. Since there are no products approved to kill adult heartworms in cats, heartworm prevention is key.
- Hookworms can be ingested or penetrate your cat’s skin. When they’re fully grown, hookworms attach to the intestinal wall, and can leave bleeding ulcers behind.
HUMAN WARNINGS: Children should not come in contact with the application site for 30 minutes after application.


Advantage Multi® for Cats can also be safely used on ferrets.
-
It’s the only FDA-approved product indicated for killing adult fleas, treating flea infestations and preventing heartworm disease in ferrets.*
*Advantage Multi® for Cats (0.4 mL) is indicated for ferrets that weigh at least 2 pounds.
