How to choose the right treatment for your cat
You want flea and worm cover in one product
Bravecto Plus covers fleas, ticks, and intestinal worms in a single 3-month spot-on. NexGard Spectra, Advocate, and Moxiclear cover fleas and worms monthly — no separate wormer needed.
You want the least frequent dosing
Bravecto Plus is dosed every 3 months — the least frequent option for cats. The Seresto collar lasts 8 months but covers fleas and ticks only, so a separate wormer is still needed.
Your cat also needs tick protection
Bravecto Plus, NexGard Spectra, Revolution Plus, Frontline Plus, and the Seresto collar all offer tick coverage. Advocate and Moxiclear do not cover ticks.
You have a kitten
Most treatments are safe from 8–9 weeks of age and a minimum weight of around 0.8–1 kg depending on the product. Always check the label. NexGard Spectra is approved from 9 weeks and is a popular choice as it also covers intestinal worms common in young cats.
Your cat is strictly indoors
Indoor cats still need regular flea treatment — fleas can enter the home on clothing, shoes, or other pets. A monthly spot-on or 3-monthly Bravecto Plus keeps them protected without the need for tick coverage if they never go outside.
You want flea-only protection at a lower price
Advantage kills fleas on contact without your cat needing to be bitten first. It's a straightforward monthly spot-on for cats that don't need worm or tick cover included. A separate wormer such as Drontal should be used every 3 months alongside it.

Frequently asked questions
How can I tell if my cat has fleas?
Signs of fleas in cats include frequent scratching, biting or over-grooming, small black specks ("flea dirt") in the coat, hair loss, skin irritation, and seeing live fleas moving through the fur. Some cats develop flea allergy dermatitis and may show intense itching even when only a few fleas are present. If fleas are found, prompt treatment and environmental control can help prevent an infestation from spreading.
How often should I treat my cat for fleas?
Monthly treatments need to be applied every 28–30 days. Bravecto Plus is the exception — it is dosed every 3 months. Year-round treatment is recommended in New Zealand, where fleas remain active in the warmer months and can persist indoors throughout winter.
Do indoor cats need flea treatment?
Yes. Fleas can be carried into the home on clothing, shoes, or other pets, and flea eggs can persist in carpet and soft furnishings for months. Indoor cats are at lower risk than outdoor cats, but regular treatment is still recommended by vets.
Can I use dog flea treatment on my cat?
No — never. Many dog flea treatments contain permethrin, which is highly toxic to cats and can be fatal even in small amounts. Always use a product specifically labelled for cats. If a dog in your household has been treated with a permethrin-containing product, keep your cat away until the product has fully dried.
Does my cat need a separate wormer?
Not if you use an all-in-one product. Bravecto Plus, NexGard Spectra, Advocate and Moxiclear provide protection against common intestinal worms in a single treatment. If you use a flea-only product, a separate worming programme may be required depending on your cat's risk factors and veterinary advice.
What is the difference between Bravecto Plus and NexGard Spectra for cats?
Both are all-in-one spot-on treatments covering fleas, ticks and intestinal worms. The main difference is duration. Bravecto Plus is dosed every 3 months, while NexGard Spectra is applied monthly. If you prefer less frequent treatment, Bravecto Plus is the better option.
What age can kittens start flea treatment?
Most treatments are approved from 8–9 weeks of age and a minimum weight of around 0.8–1 kg. Always check the product label. NexGard Spectra is approved from 9 weeks and is commonly recommended for kittens as it also treats the intestinal worms young cats often carry.
How quickly does cat flea treatment work?
NexGard Spectra begins killing fleas within 6 hours of application. Bravecto Plus kills fleas within 12 hours. Advantage kills fleas on contact — they do not need to bite your cat for the treatment to work, which is useful for cats with flea allergy dermatitis.
Can my cat be bathed after a spot-on treatment?
Most spot-on treatments recommend keeping your cat dry for 24–48 hours after application. After that they are water-resistant. However, frequent bathing can reduce effectiveness over time, so avoid washing the application area unnecessarily.
Do I need a vet prescription for these products?
No. All products in our range are available over the counter in New Zealand without a prescription and are approved for sale under NZ regulations.
What if I miss a dose?
Apply the treatment as soon as you remember, then reset your schedule from that new date. A gap leaves your cat temporarily unprotected, particularly if they spend time outdoors or live with other pets.
What is the best flea treatment for cats in NZ?
Bravecto Plus and NexGard Spectra are among the most popular veterinary flea treatments in New Zealand because they provide protection against fleas, ticks and intestinal worms. The best option depends on your cat's age, lifestyle and whether you prefer monthly or 3-monthly treatment.
