Advocate's easy-to-use spot-on provides fast relief from fleas, prevents deadly heartworm and protects both your cat and your family from most gastrointestinal worms. Advocate provides a comprehensive parasite protection which is applied monthy. Advocate is the only product that kills the two parasites causing lungworm disease in cats, which causes irreversible damage to the lungs. Advocate creates a flea-free home fast. It affects re-infesting fleas within 3 to 5 minutes and kills them within 1 hour. Unlike many other treatments (especially tablets), Advocate kills flea larvae in your cat's surroundings within 20 minutes of contact with the active ingredient (in shed skin and hair debris) - breaking the flea lifecycle. It even provides protection to your cat when it comes into contact with other animals that have fleas. Advocate kills fleas on contact, so cats don't suffer painful bites, reducing the incidence of Flea Allergy Dermatitis. Unlike other gastrointestinal worming products, Advocate doesn't just kill the adult worms present at the time of treatment. Advocate also kills larvae and immature stages of roundworms and hookworms. With monthly use, Advocate reaches a steady state concentration in the blood to prevent re-infestation with heartworm and intestinal nematode worms between treatments. Advocate also kills ear mites and feline mange mites. Advocate is tough on nasty parasites, but gentle on your cat, and is safe for use from 9 weeks of age, and is water-resistant. Advocate is also registered for flea and heartworm control in ferrets weighing 0.8 kg or more.
