Advocate for Cats Purple is a monthly spot-on parasite treatment for cats weighing over 4kg. Applied to the back of the neck once a month, it provides combined flea control, heartworm prevention, and gastrointestinal worm treatment in a single product — covering three distinct parasite threats without juggling separate treatments.

Applied monthly to the back of the neck, the spot-on kills fleas on contact and prevents further infestation while simultaneously providing systemic protection against heartworm. It also treats common gastrointestinal nematodes including roundworm, hookworm, and lungworm. The formulation is water resistant after application, making it practical for cats with outdoor access. As a broad-spectrum treatment combining multiple active parasite classes, it removes the need to remember separate monthly flea, heartworm, and worm treatment dates.

Advocate is a practical choice for cat owners who want to consolidate flea, heartworm, and worm prevention into a single monthly product. The once-monthly schedule removes the complexity of tracking multiple treatment dates, and the water-resistant formula suits cats that won't stay dry.
