Advantage II for Cats
Topical flea control treatment for cats
Advantage II for cats is a reformulated version of Advantage for Cats, a topical flea treatment that earns good ratings from vets. The new version contains two ingredients, one that kills adult fleas and one that prevents immature fleas from developing. However, unlike Frontline Plus, Advantage II doesn't kill ticks. Advantage II is applied once monthly to the back of the neck, and its effectiveness is not diminished by water exposure. You can purchase a four- to 12-month supply of Advantage online without a vet's prescription, but the cat should be at least 8 weeks old.
