Introduction
Flea infestations pose dual threats to cats: itching, dermatitis, and tapeworm exposure (via flea ingestion). Selecting a dewormer that addresses both fleas and intestinal parasites is crucial in flea-prone households. This guide helps you choose the best cat dewormer for such environments.

1. Understand the Parasite-Flea Connection

• Tapeworm Transmission: Cats ingest infected fleas while grooming; tapeworm cysts hatch in the digestive system.

• Concurrent Infestations: Fleas can carry other pathogens (e.g., Bartonella), compounding health risks.

2. Topical (Spot-On) Combination Treatments

• Selamectin (Revolution®)

  • Spectrum: Flea prevention, heartworm, roundworms, hookworms, ear mites.

  • Application: Monthly spot-on between shoulder blades.

  • Benefits: Broad-spectrum coverage minimizes the need for multiple products.

• Fipronil/S-Methoprene (Frontline Plus®)

  • Spectrum: Flea and tick prevention; does not directly target intestinal worms.

  • Pair with Dewormer: Combine with a monthly pyrantel-based oral dewormer for tapeworm control.

3. Oral Deworming Tablets for Tapeworms

• Praziquantel (Droncit® Tablets)

  • Dosage: 5–7.5 mg/kg orally as a single dose.

  • Frequency: Administer every 1–2 months in flea-endemic seasons.

  • Administration Tip: Offer inside a small portion of soft food to improve acceptance.

4. Integrated Flea Control Strategies

• Environmental Treatment

  • Vacuum carpets, furniture, and bedding weekly to eliminate flea eggs and larvae.

  • Use veterinary-grade home sprays or foggers with insect growth regulators (IGRs).

• Preventive Measures

  • Bathe/eliminate fleas on other pets; treat all household animals concurrently.

  • Wash bedding in hot water weekly.

5. Monitoring and Veterinary Consultation

• Fecal Testing: Quarterly fecal exams to detect tapeworm segments or eggs.

• Physical Exams: Check for flea dirt (tiny black specks) in the cat’s coat weekly.

• Weight and Behavior Monitoring: Persistent scratching, hair loss, or weight loss warrant immediate vet attention.

Conclusion
In flea-infested homes, the optimal cat dewormer regimen includes a combination of topical flea-and-parasite preventives like Revolution® and targeted oral tapeworm treatments such as Droncit®. Integrated environmental control and regular veterinary check-ups ensure your cat remains free from fleas and intestinal parasites.
