Flea drops aren't working for the cat, what should I do? - briefly
If the applied «flea drops» do not control the infestation, confirm correct dosage, application site, and product compatibility with the cat’s weight and health condition. Contact a veterinarian to discuss oral treatments, prescription collars, or a revised control regimen.
Flea drops aren't working for the cat, what should I do? - in detail
When topical flea treatments do not eliminate the parasite burden on a cat, several factors may be responsible. Resistance to the active ingredient can develop after repeated use of the same product. Incorrect dosage often results from miscalculating the cat’s weight or using an adult‑strength dose on a kitten. Application errors include missing the skin surface, allowing the cat to lick the spot before the medication dries, or applying the drop to a shaved area where absorption is reduced. Underlying health conditions, such as skin disorders or hormonal imbalances, can diminish efficacy. Finally, a heavily infested environment may re‑introduce fleas faster than the treatment can act.
To diagnose and correct the problem, follow these steps:
- Verify that the selected product matches the cat’s weight range; consult the label wording «For cats weighing 2‑5 kg» or similar.
- Measure the cat’s current weight and adjust the dose accordingly.
- Apply the drop directly to the skin at the base of the neck, ensuring the fur is parting to expose the skin.
- Allow the cat to remain undisturbed for at least 30 minutes to prevent licking.
- Repeat the application according to the manufacturer’s schedule, typically every 30 days.
- Conduct a thorough inspection of the home: vacuum carpets, wash bedding, treat all pets, and use an environmental spray labeled «kills fleas at all life stages».
If topical treatment continues to fail, consider alternative modalities:
- Oral systemic products that deliver a lethal dose through the bloodstream.
- Flea‑preventive collars containing imidacloprid or selamectin.
- Medicated shampoos applied weekly for two to three weeks.
- Professional pest‑control services for severe infestations.
After implementing corrective measures, monitor the cat for signs of flea activity over a two‑week period. Record any observed bites, scratching, or live fleas. If no reduction is evident, schedule a veterinary consultation to explore prescription‑strength options, assess for possible resistance, and evaluate the cat’s overall health.
