NexGard Spectra Spot-On (purple) is a monthly parasite prevention treatment for kittens and small cats weighing 0.8–2.4 kg, suitable from 8 weeks of age. Sold as a 3-pack, it's a prescription product that provides complete protection in a single monthly application, without needing to combine separate flea, worming, and heartworm treatments.

A single monthly application covers fleas, ticks (including paralysis tick), mites, heartworm, lungworm, and intestinal worms — including tapeworm. The syringe-style applicator is designed to part the fur and deliver the solution at the back of the neck with minimal fuss for the cat. As Australia's first all-in-one spot-on for cats, the formulation covers the full parasite risk profile relevant to Australian conditions.

Owners who've previously managed separate flea, worming, and heartworm schedules tend to appreciate the simplicity of tracking one product on one date. Complete coverage means nothing falls through the gaps between rotation schedules. A valid veterinary prescription is required to purchase.
