Seresto® Flea and Tick Collar for Cats

What It Is:

Seresto® is a long-lasting flea and tick collar designed for cats, providing up to eight months of continuous protection with a single application. It slowly releases two active ingredients that distribute over the skin and coat to kill and repel fleas, ticks, lice, and mites without the need for monthly reapplication.

🐾 What It Treats and Prevents

Seresto® collars protect against:

• Fleas — kills adult fleas and prevents reinfestation
• Ticks — repels and kills black-legged ticks, lone star ticks, and American dog ticks
• Cheyletiella mites (“walking dandruff”)
• Lice — biting lice species in cats
• Sarcoptic mange mites in some off-label uses

Because it covers the entire coat, Seresto® also helps reduce the risk of flea allergy dermatitis.

🧪 Active Ingredients

Seresto® collars contain:

• Imidacloprid — targets and kills fleas by disrupting their nervous system
• Flumethrin — repels and kills ticks, mites, and lice through neurotoxicity

These actives are embedded in the collar matrix and released at low doses over months for a steady, even distribution.

🐾 How to Use It

To apply Seresto®:

1. Remove the collar from the package and unroll it
2. Place it around the cat’s neck, adjusting for a snug but comfortable fit (allow two fingers between collar and neck)
3. Trim any excess length, leaving the indicator clip visible
4. Replace collar every eight months for continuous protection

Do not remove the collar for bathing or swimming; it is waterproof and remains effective.

🔍 Safety and Precautions

Seresto® collars are generally safe but observe for:

• Mild irritation at the neck or collar site
• Excessive grooming or drooling if the cat licks the collar
• Allergic reactions such as itching or swelling

Use with caution in cats that are:

• Under ten weeks of age or weighing less than the minimum on the label
• Pregnant or nursing, unless directed by a veterinarian
• Known sensitivity to pyrethroids or neonicotinoids

If irritation persists beyond 48 hours, remove the collar and consult your veterinarian.

🩺 Prognosis

With correct use:

• Fleas and ticks are controlled within 24 to 48 hours of application
• Continuous protection lasts up to eight months without reapplication
• Works best when all pets in the household are protected and environment is managed

Because it eliminates the need for monthly dosing, Seresto® improves compliance and overall parasite control.

💡 Cat Owner Note

Seresto® takes the hassle out of parasite prevention. No monthly drops, no pills, no applications. Just one collar for eight months of worry-free protection. Make sure it fits properly, check the indicator clip, and enjoy the peace of mind that comes with long-term coverage.
