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 environment – adult 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 absorption – skin 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:
- Verify the cat’s weight and select a product with the appropriate concentration.
- Rotate insecticide classes annually or follow a veterinarian‑recommended resistance‑management plan.
- 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.
- Consult a veterinarian if the cat shows skin disease, allergies, or other health problems that could interfere with medication uptake.
- Store all flea control agents according to manufacturer instructions, away from direct sunlight and extreme temperatures.
- 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.
