At Smartway Pet Supplies, you can order genuine NexGard SPECTRA for cats online without a vet prescription, with fast international shipping to the USA, Canada, and beyond.

What Does NexGard SPECTRA for Cats Protect Against?

A single monthly application delivers complete internal and external parasite control in one easy-to-use spot-on applicator. NexGard SPECTRA for cats targets:

• Fleas — kills fleas fast and helps prevent Flea Allergy Dermatitis (FAD)
• Ticks — including paralysis ticks and bush ticks
• Ear mites — treats and controls ear mite infestations
• Heartworm — monthly prevention of heartworm disease
• Roundworms & hookworms — treats and controls common intestinal nematodes
• Lungworms — effective against feline lungworm infections
• Tapeworms — the only broad-spectrum feline parasiticide that also treats tapeworms

How Does NexGard SPECTRA Work?

NexGard SPECTRA combines three clinically proven active ingredients in a single topical dose:

• Esafoxolaner — a next-generation isoxazoline compound specially formulated for cats that targets and kills fleas, ticks, and mites by disrupting their nervous system
• Eprinomectin — a macrocyclic lactone that prevents heartworm disease and treats roundworms, hookworms, and lungworms
• Praziquantel — a trusted anthelminthic that eliminates tapeworm infections

Together, this triple-action formula delivers full-spectrum protection against both ectoparasites and endoparasites in a single monthly treatment — no separate wormer needed.

No Prescription Required — How Is That Possible?

In the United States and Canada, NexGard SPECTRA is typically only available through veterinary clinics. However, Smartway Pet Supplies is an Australian-based retailer, and in Australia, NexGard SPECTRA is sold as an over-the-counter product. This means we are not required to collect a prescription to supply and ship these products internationally. When you order from Smartway, you are purchasing from an Australian retailer and importing the product into your own country. For a full explanation of how this works, see our page on does NexGard require a prescription.

Which NexGard SPECTRA Size Is Right for My Cat?

NexGard SPECTRA Spot-On for Cats is available in two weight-based sizes. Choosing the correct size for your cat's weight is essential for effective treatment:

• Purple (Small) — for cats weighing 1.8–5.3 lbs (0.8–2.5 kg), including kittens 8 weeks and older
• Yellow (Large) — for cats weighing 5.5–16.5 lbs (2.5–7.5 kg)

If your cat weighs more than 16.5 lbs, use two applications from the appropriate weight ranges. Always apply based on your cat's current body weight.

How to Apply NexGard SPECTRA Spot-On for Cats

The precision syringe-style applicator is designed to make monthly treatment quick and stress-free:

1. Prepare: Pull back the plunger slightly, then twist and remove the protective cap
2. Part the fur: Gently part the hair along the midline of the neck, between the base of the skull and the shoulder blades, until the skin is visible
3. Apply: Place the applicator tip directly on the skin and press the plunger firmly to dispense the entire contents in a single spot
4. Done: Allow the area to dry. Do not touch the application site until dry

Apply once every month, year-round, for continuous parasite protection.

Is NexGard SPECTRA Safe for Cats?

NexGard SPECTRA is FDA-approved and manufactured by Boehringer Ingelheim, one of the world's leading animal health companies. It is safe for use in kittens from 8 weeks of age and weighing 1.8 lbs or more. Side effects are uncommon but may include mild, temporary skin irritation at the application site or occasional gastrointestinal signs. Use with caution in cats with a history of neurological disorders. The safety of NexGard SPECTRA has not been evaluated in breeding, pregnant, or lactating cats.

How Does NexGard SPECTRA Compare to Other Cat Treatments?

Not sure which product is right for your cat? Here's how NexGard SPECTRA stacks up against the other top options in our cat range:

• Revolution Plus for Cats — monthly spot-on covering fleas, ticks, heartworm, ear mites, and intestinal worms. A popular alternative for cats where tapeworm coverage is not the primary concern.
• Bravecto for Cats — extended-duration spot-on providing up to 2–3 months of flea and tick protection per dose. Ideal for owners who prefer less frequent applications.
• Advocate for Cats — monthly spot-on targeting fleas, heartworm, ear mites, hookworms, and roundworms. Does not cover ticks or tapeworms.
• Paragard Allwormer for Cats — an oral tablet allwormer for roundworm, hookworm, whipworm, and tapeworm. Best used alongside a separate flea and tick treatment.

NexGard SPECTRA is the only option that combines all of the above in a single monthly dose — making it the most complete all-in-one solution available for cats.
