Introduction
Summer brings warmer temperatures and increased flea activity, heightening the risk of tapeworm infections and other parasites in cats. A seasonal deworming strategy, aligned with flea prevention, is essential to protect felines during high-risk months. This guide outlines a summer-focused deworming plan to keep cats healthy year-round.

1. Understanding Flea-Transmitted Parasites

• Tapeworm Lifecycle:

  • Flea larvae ingest tapeworm eggs in the environment; adult fleas harbor cysticercoids.

  • Cats ingest infected fleas while grooming, leading to tapeworm infection within 24 hours.

• Other Summer Parasites:

  • Hookworms and roundworms can also be transmitted through contaminated soil or prey.

2. Pre-Summer Preparations (Late Spring)

• Flea Prevention Initiation:

  • Start monthly spot-on flea and parasite control (e.g., selamectin or fipronil/ (s)-methoprene) in May.

  • Inspect and treat all household pets simultaneously to eliminate flea reservoirs.

• Environmental Treatment:

  • Vacuum carpets, curtains, and pet bedding weekly.

  • Wash bedding in hot water and use IGR (insect growth regulator) sprays on indoor surfaces.

• Baseline Deworming:

  • Perform a fecal exam in late spring to identify any residual parasite burdens.

  • Administer a broad-spectrum dewormer (fenbendazole or pyrantel/praziquantel) if positive.

3. Summer Deworming Schedule (June–August)

• Monthly Spot-On Treatments:

  • Use products like Revolution® (selamectin) for combined flea, ear mite, and intestinal parasite control.

  • Reapply every 30 days even if the cat does not go outdoors.

• Tapeworm-Specific Deworming:

  • In July (peak flea season), administer praziquantel (5–7.5 mg/kg orally) to address potential tapeworm exposure.

  • Follow up with a fecal exam 2–3 weeks later to confirm eradication.

• Combination Topical Options:

  • Advantage Multi® (moxidectin/imidacloprid) offers comprehensive protection; apply monthly for intestinal parasite and flea control.

4. Post-Summer Maintenance (Early Fall)

• Fecal Recheck:

  • Conduct a fecal float in September to detect any lingering summer parasites.

  • Adjust future deworming frequency if persistent infections are found.

• Environmental Deep Clean:

  • Steam-clean carpets and upholstery to kill flea eggs and larvae.

  • Replace or thoroughly disinfect outdoor cat shelters and bedding.

5. Long-Term Year-Round Plan

• Quarterly Deworming:

  • Outside peak summer, administer broad-spectrum dewormer (fenbendazole or pyrantel/praziquantel) every 3 months.

• Monthly Flea Control:

  • Continue year-round for indoor-outdoor cats; reduces intermediate flea hosts.

• Regular Vet Visits:

  • Biannual wellness checks with fecal exams to monitor parasite status.

  • Adjust strategy based on local flea prevalence and individual cat risk factors.

Conclusion
A summer-focused deworming strategy that combines monthly topical treatments, targeted tapeworm control, and rigorous environmental management effectively combats flea-transmitted parasites. Coupled with year-round preventive measures, this approach ensures cats remain healthy and parasite-free.
