NexGard Spectra Spot-On for Cats 5.5–16.5 lbs (2.5–7.5 kg) – Yellow

NexGard Spectra Spot-On for Cats 5.5–16.5 lbs (2.5–7.5 kg) – Flea, Tick & Heartworm Prevention (Yellow)

NexGard Spectra Spot-On for Cats delivers complete monthly parasite protection in a single easy-to-apply topical. Combining esafoxolaner, eprinomectin, and praziquantel, NexGard Spectra (Yellow) protects adult cats weighing 5.5–16.5 lbs (2.5–7.5 kg) against fleas, ticks, heartworm, intestinal worms (roundworm, hookworm), and tapeworm — six parasites covered in one monthly application.

What NexGard Spectra Protects Against

• Fleas: Kills adult fleas fast and prevents new infestations from establishing in your home.
• Ticks: Controls tick species that affect cats — especially important for outdoor cats and cats in wooded areas.
• Heartworm: Prevents heartworm disease, transmitted by infected mosquitoes (indoor cats are at risk too).
• Roundworm and hookworm: Treats the two most common intestinal worms in cats.
• Tapeworm: Treats tapeworm — commonly picked up from ingesting fleas during grooming, or from hunting small prey.

Why Cat Owners Choose NexGard Spectra

• One product replaces three: Skip the separate flea/tick spot-on, heartworm pill, and all-wormer — one monthly tube covers all six parasites.
• No pilling, no fighting: A topical spot-on is easier than pills or chews for most cats — just apply between the shoulder blades.
• Includes tapeworm coverage: Not all monthly cat preventatives include tapeworm. NexGard Spectra does — a meaningful upgrade for cats that hunt or have flea exposure.
• Cat-only formulation: Dosed and formulated specifically for cats. Never use a dog product on your cat — many contain permethrin, which is highly toxic to cats.
• Properly sized: The Yellow pack is dosed for cats 5.5–16.5 lbs — covers most adult cats. Use Purple for smaller cats and kittens.

How NexGard Spectra Works

NexGard Spectra Spot-On for Cats combines three trusted active ingredients in one tube:

• Esafoxolaner is absorbed through the skin and kills fleas and ticks when they bite — systemic protection rather than just surface contact.
• Eprinomectin prevents heartworm and treats common intestinal worms (roundworm, hookworm).
• Praziquantel specifically targets tapeworm at all life stages, including the segments cats often pass after a flea infestation.

Who It’s For

• Adult cats weighing 5.5–16.5 lbs (2.5–7.5 kg)
• Cats 8 weeks of age and older
• Healthy cats (consult your vet before use in pregnant, nursing, or chronically ill cats)

How to Apply NexGard Spectra Spot-On

1. Part the fur at the base of the skull, between the shoulder blades, until you can see the skin.
2. Place the tube tip directly on the skin and squeeze the full contents onto the skin in one spot.
3. Avoid getting the product on the fur — it works through the skin, not the coat.
4. Keep your cat dry for 24 hours after application — no bathing or swimming.
5. Repeat once monthly, on the same date each month for continuous protection.

Possible Side Effects

NexGard Spectra is well tolerated by most cats. Mild side effects can include temporary scratching at the application site, brief hair loss or skin reaction at the site, or mild lethargy. Contact your veterinarian if anything persists or seems unusual.

Frequently Asked Questions

My cat is over 16.5 lbs — can I still use the Yellow pack?
The Yellow pack is dosed for cats up to 16.5 lbs (7.5 kg). For cats over that weight, talk to your vet — depending on your cat’s exact weight and health, they may recommend a different product or a vet-supervised dosing approach. Don’t double-up packs without veterinary guidance.

How fast does NexGard Spectra start working?
Fleas start dying within 24 hours of application, and continuous protection builds within 48 hours. Each application provides a full month of coverage.

Is the spot-on safe if my cat grooms the application site?
Once the spot-on has dried (usually within an hour), it’s safe even if your cat grooms the area. The product is absorbed through the skin, not by ingestion. For the first hour, distract your cat to let it dry properly.

Does NexGard Spectra cover tapeworm? My indoor cat keeps getting it.
Yes — tapeworm coverage is one of NexGard Spectra’s key advantages. Indoor cats typically get tapeworm from ingesting fleas during grooming, so a single product that covers both the fleas and the tapeworm interrupts that cycle effectively. The praziquantel active ingredient specifically targets tapeworm.

Do I need a prescription to buy NexGard Spectra?
No — SmartWay Pet Supplies ships NexGard Spectra over the counter to customers across the US and Canada. No prescription or vet authorization required at checkout.

Should I dose year-round for an indoor cat?
Yes — even indoor cats benefit from year-round protection. Fleas hitch rides on humans, dogs, and through open doors; mosquitoes carrying heartworm get inside; and tapeworm can develop without obvious flea infestation. Continuous monthly dosing is the safest approach.
