NexGard Spectra has long been a trusted name in parasite protection for dogs — but cat owners in New Zealand can now also benefit from this powerful all-in-one treatment. In this comprehensive guide, we’ll cover everything you need to know about NexGard Spectra for Cats, including how it works, what it protects against, dosing instructions, safety, side effects, and where to buy it in NZ.
What Is NexGard Spectra for Cats?
NexGard Spectra for Cats is a monthly topical treatment that provides broad-spectrum protection against parasites. Unlike the chewable format used for dogs, the feline version is a spot-on liquid applied to the skin, formulated specifically for the physiology of cats.
It combines two active ingredients:
- Esafoxolaner: Kills adult fleas and ticks.
- Eprinomectin & Praziquantel: Provides broad internal parasite control, including roundworms, hookworms, and tapeworms.
This all-in-one protection makes NexGard Spectra one of the most comprehensive treatments available for NZ cats.
What Parasites Does It Protect Against?
NexGard Spectra for Cats protects against a wide range of external and internal parasites, including:
- Fleas: Kills adult fleas quickly and prevents egg-laying.
- Ticks: Effective against common NZ tick species.
- Roundworms and Hookworms: Controls intestinal worms that commonly infect cats.
- Tapeworms: A rare inclusion in many spot-ons, but covered here.
This means your cat is protected from parasites that cause irritation, illness, and even zoonotic infections (transmissible to humans).
How to Apply NexGard Spectra
NexGard Spectra for Cats is a once-a-month treatment applied to the back of your cat’s neck, between the shoulder blades. This location prevents your cat from licking the product during grooming.
- Open the single-use tube.
- Part the fur at the base of your cat’s neck.
- Apply the contents directly onto the skin.
- Do not bathe or shampoo your cat for 2–3 days post-application.
Always follow the instructions provided in the pack or consult your veterinarian for application tips if your cat is difficult to medicate.
When Can Kittens Start NexGard Spectra?
NexGard Spectra is safe for kittens from 8 weeks of age and weighing at least 0.8 kg. Regular monthly dosing helps establish consistent protection during your kitten’s vulnerable growth stage.
Side Effects to Be Aware Of
NexGard Spectra for Cats is generally well-tolerated, with only mild side effects reported in rare cases:
- Temporary hair loss or mild irritation at the application site
- Lethargy or reduced appetite
- Salivation or licking (if cat ingests product)
If your cat experiences more severe symptoms or persistent discomfort, consult your vet immediately. Most side effects are mild and resolve within 24–48 hours.
Can NexGard Be Used with Other Medications?
In most cases, yes — but always consult your vet before combining treatments. NexGard Spectra is designed as a stand-alone comprehensive treatment and typically eliminates the need for additional flea, tick, or worm products.
Monthly Schedule Reminder
To maintain continuous protection, NexGard Spectra must be given monthly. It can help to set a phone reminder.
Feeding & Health Tips for Cats on NexGard
- Ensure your cat is eating a balanced, age-appropriate diet for optimal immune support.
- Keep litter boxes clean and indoor areas vacuumed regularly to reduce flea exposure.
