Advantage II Large Cat Vet-Recommended Flea Treatment & Prevention | Cats Over 9 lbs. | 2-Month Supply 2-Pack
Overview
Advantage II Large Cat is a monthly topical flea treatment formulated for cats and kittens weighing more than 9 pounds. Each application delivers fast-acting, contact-based flea control that begins killing adult fleas within 12 hours and continues to prevent re-infestation for 30 days by targeting adult fleas, eggs and larvae. This 2-pack provides two monthly doses, making it a practical choice for cat owners who need ongoing protection without daily dosing. It’s favored by many veterinarians because it interrupts the flea life cycle, reduces household flea populations, and is simple to apply as a spot-on treatment. Ideal for multi-cat homes and indoor/outdoor cats where consistent, monthly control is important to protect comfort and reduce parasite-related health risks.
