Почему не выводятся блохи у кота? - briefly

Fleas remain on a cat when the chosen treatment is ineffective, the insects are resistant, re‑infestation occurs, or the medication is applied incorrectly. Using a veterinarian‑approved product correctly and treating the environment simultaneously resolves the problem.

Почему не выводятся блохи у кота? - in detail

Fleas may persist on a cat when treatment does not fully break the parasite’s life cycle. Incomplete eradication often stems from one or more of the following factors:

  • Incorrect dosage or application – applying too little product, missing the recommended interval, or using a formulation unsuitable for the cat’s weight allows surviving adults and newly hatched larvae to continue reproducing.
  • Resistance to active ingredients – repeated use of the same class of insecticide (e.g., pyrethroids, neonicotinoids) can select for resistant flea populations, rendering the product ineffective.
  • Failure to treat the environmentadult fleas lay eggs that fall off the host into bedding, carpets, and upholstery. Without simultaneous indoor treatment (sprays, powders, or vacuuming), emerging fleas re‑infest the cat.
  • Health conditions affecting absorptionskin disorders, excessive grooming, or oily coats can impede topical absorption, while gastrointestinal problems may reduce the efficacy of oral medications.
  • Improper storage – exposure to heat, light, or moisture degrades many flea products, decreasing their potency before use.
  • Concurrent use of incompatible products – mixing shampoos, collars, or spot‑on treatments that contain antagonistic chemicals can neutralize each other’s action.

Addressing these issues requires a systematic approach:

  1. Verify the cat’s weight and select a product with the appropriate concentration.
  2. Rotate insecticide classes annually or follow a veterinarian‑recommended resistance‑management plan.
  3. Treat the living area with an environmental flea control product, wash all bedding at high temperature, and vacuum carpets thoroughly each day for two weeks.
  4. Consult a veterinarian if the cat shows skin disease, allergies, or other health problems that could interfere with medication uptake.
  5. Store all flea control agents according to manufacturer instructions, away from direct sunlight and extreme temperatures.
  6. Avoid simultaneous use of multiple flea products unless explicitly approved by a professional.

By ensuring correct dosing, combating resistance, eliminating environmental reservoirs, and maintaining the cat’s health, the flea population can be effectively reduced and eventually eliminated.
