Senergy Topical Solution for Cats, 5.1-15 lbs, (Blue Box)

Senergy Topical Solution for Cats 5.1-15 lbs

Broad-Spectrum Parasite Protection Made Easy

Senergy Topical Solution for Cats 5.1-15 lbs is a once-a-month spot-on flea and parasite control treatment designed to protect your feline from multiple internal and external parasites. It contains selamectin, a powerful parasiticide that targets fleas, ear mites, roundworms, hookworms, and even prevents heartworm disease in cats weighing between 5.1 to 15 lbs.

This prescription-strength formula is ideal for both treatment and prevention, offering comprehensive protection in a single, easy-to-apply dose. Senergy is comparable to Revolution for Cats, providing the same active ingredient and spectrum of control—at a more cost-effective price, making it a top choice for value-conscious pet parents.

Prescription items are NON-RETURNABLE and NON-REFUNDABLE.

Choose the Right Senergy for Your Cat or Kitten

Ensure your feline receives the correct dosage and protection by selecting the Senergy product that matches their weight and age. Using the appropriate formulation guarantees safety and effectiveness.

• Senergy for Kittens Up to 5 lbs – gentle enough for kittens over 6 weeks old and under 5 lbs in weight.
• Senergy for Cats 15.1–22 lbs – formulated for heavier or larger cat breeds like Ragdolls and Maine Coons.

Always verify your cat’s current weight before applying any parasiticide. Senergy is species-specific—do not use dog formulations on cats.

What Are the Key Benefits of Senergy Topical Solution for Small Cats?

Senergy doesn’t just treat—it prevents infestations before they start. Here’s how it protects your cat comprehensively:

• Kills adult fleas and prevents flea eggs from hatching (breaking the lifecycle)
• Prevents heartworm disease caused by Dirofilaria immitis
• Treats and controls ear mite infestations (Otodectes cynotis)
• Eliminates roundworms and hookworms, reducing zoonotic risk
• Waterproof and long-lasting, maintaining efficacy even after bathing
• Once-monthly dosing, no pills or struggle needed

Unlike oral tablets or collars, Senergy acts through transdermal absorption, ensuring whole-body protection without stressing your cat.

How Does Senergy Compare to Other Flea & Parasite Treatments?

How Should I Use Senergy for My Cat?

Apply Senergy once every 30 days directly to the skin on the back of your cat’s neck at the base of the skull. Always use the correct dosage based on your cat’s body weight (5.1 to 15 lbs for this product).

Application Instructions:

1. Remove one pipette from the foil tray.
2. Hold the pipette upright and press cap down until you hear a click (indicating it’s punctured).
3. Part the fur at the base of your cat’s neck.
4. Squeeze the entire content directly onto the skin.

What Is the Active Ingredient in Senergy Topical Solution for Cats?

• Selamectin (60 mg/mL) – a macrocyclic lactone belonging to the avermectin class. It binds to chloride ion channels in parasite nerve and muscle cells, leading to paralysis and death.

This ingredient is systemically absorbed and then distributed through the skin and bloodstream to kill parasites effectively.

Are There Any Side Effects of Senergy for Cats?

While generally safe, some cats may experience:

• Mild hair loss at the application site
• Temporary skin irritation or redness
• Digestive upset (vomiting/diarrhea)
• Lethargy or inappetence (rare)

If any symptoms persist beyond 24–48 hours, consult your veterinarian immediately.

What Warnings or Precautions Should I Know About?

• For cats only, and not for use in kittens under 8 weeks old.
• Do not use on sick, debilitated, or underweight cats without vet consultation.
• Avoid contact with the treated area until dry.
• Keep away from children and other pets during application.
• Store below 30°C and avoid freezing.
