Advocate for Cats Over 4kg is a monthly spot-on treatment covering fleas, heartworm, and intestinal worms in a single application. The purple pack is sized specifically for cats weighing more than 4 kilograms, providing full-spectrum parasite protection without requiring multiple separate products.

The active ingredients — imidacloprid and moxidectin — work through two mechanisms. Imidacloprid kills fleas on contact before they can bite or lay eggs; moxidectin targets heartworm larvae, roundworm, and hookworm systemically. Applied to the skin at the back of the neck, the treatment is absorbed and distributed without requiring the cat to ingest anything. It also reduces the risk of human roundworm transmission from household cats.

Advocate suits multi-cat households or cats with outdoor access where consistent, broad-spectrum protection matters. A single monthly application replaces the need to juggle separate flea, heartworm, and worming products on different schedules.
