Cat lovers choose Advantage XD for double the lasting protection against fleas vs. other 1-month options. Advantage XD for small cats and kittens packs two full months of treatment and continuous protection in each dose, so your cat is protected for longer than the traditional 1-month formula.* If your cat has already tousled with fleas, you’ll love that Advantage XD topical treatment starts killing fleas within 30 minutes to 4 hours through contact so they don’t have to bite and die. And with Advantage XD extended duration formula, that flea prevention remains effective for 8 weeks, outlasting the typical 6-week flea life cycle and preventing reinfestation. Find Advantage XD topical flea treatment available in a variety of pack sizes, from 2 months protection (1 dose), to 4 months protection (2 doses), or 8 months protection (4 doses). This fragrance-free formula contains Spinetoram, a naturally derived, Green Chemistry Award-winning** ingredient. Advantage XD flea infestation prevention is effective on both indoor and outdoor cats. Your cat should be at least 8 weeks old and between 1.8 and 9 lbs. to use Advantage XD for small cats. Even with the squirmiest of kittens and cats, application is easy. This single, topical, spot-on application goes on the back of your cat’s neck at the base of the skull. You’ll simply place the tip of the tube on the skin and squeeze the tube to expel the entire contents directly on the skin. It's easier, there are no hard-to-swallow pills; this topical treatment goes on in seconds. See product label for more information. For the ultimate convenience in care, Advantage XD is available over the counter – no prescription needed. Once Advantage XD is applied, your cat is ready to get right back to exploring the outdoors or finding a cozy spot for a nap, while you get to enjoy peace of mind. *Based on label claims **US EPA Presidential Green Chemistry Challenge.
