Advantage II Small Cat is a vet-recommended monthly topical flea treatment designed for small cats weighing 5 to 9 lbs and at least 8 weeks of age. This Costco value pack includes an 8-month supply (8 tubes, each containing 0.0176 fl oz / 0.4 mL) of fast-acting flea protection.

Applied directly to the skin at the base of the cat's skull, Advantage II kills adult fleas, flea larvae, and flea eggs through contact alone — no biting required. It begins working within 12 hours of application and provides continuous protection for 30 full days per dose. The formula also disrupts the flea life cycle to prevent re-infestation, so reinfesting fleas are killed within 2 hours of contact.

The easy-to-use, fragrance-free formula requires no prescription and becomes waterproof within 24 hours of application. No hard-to-swallow pills or vet visit needed. To apply, part the hair at the base of the cat's skull until skin is visible, then squeeze the entire contents of one tube directly onto the skin. Avoid contact with eyes and do not allow the cat to ingest the product.
