Advocate provides comprehensive parasite protection. A convenient, easy-to-use spot-on, applied monthly. The super ingredients in Advocate provide fast relief from fleas, prevent deadly heartworm disease, and provide ongoing protection from common intestinal worms including adult and immature stages of roundworms and hookworms. Advocate is the only product that protects against both species of lungworms that cause disease in cats. Advocate also kills ear mites and feline mange mites. Unlike most other products, Advocate kills fleas on contact, and stops reinfesting fleas from biting in 3 – 5 minutes, reducing the incidence of Flea Allergy Dermatitis. Advocate is safe for kittens from 9 weeks of age and ferrets weighing 0.8 kg or more. Advocate is also water-resistant.
