Rid your home of pesky fleas with Advantage II, a fast-working, month-long flea control for your pet. Kills fleas, eggs and larvae. Killing fleas quickly is important, as it prevents them from laying eggs and helps reduce the risk of secondary problems, such as flea allergy dermatitis and tapeworms. Advantage II stops biting fleas in less than 5 minutes, over 99 percent of flea larvae within 20 minutes, at least 98 percent of fleas within 12 hours, and 100 percent of chewing lice in just 1 week. Each application of waterproof Advantage II keeps your cat free of fleas for a full month. Flea bites can cause discomfort for your pet, lead to skin infections and allergic skin reactions causing irritation, and can even transmit other disease-causing organisms. Safe for all cats 8 weeks or older that weigh over 9 pounds. Includes a 4-month supply.
