Stronghold spot-on for cat

Affordable Stronghold Flea Treatment and Wormer

What Is Stronghold?

Stronghold spot-on for cats is a broad spectrum and dependable parasite killer, that focuses on eradicating the flea infestation by killing flea eggs, flea larvae, and adult fleas. Along with external parasites like ear mites, biting lice and fleas, the monthly treatment also terminates roundworms and hookworms in cats. The unique formulation remains active for an entire month thus keeping your cat safe. Though cats have very few chances of heartworm infestation still this treatment can be used as a heartworm preventive if you are staying in areas where heartworm infestation rate is high. The easy to use topical treatment is also waterproof after the 2 hours of administration. It is also tested safe for pregnant, breeding and lactating queens.

How Does It Work?

Stronghold treats a wide range of both external and internal parasites. The solution’s active ingredient Selamectin has a high affinity for sebaceous glands and skin hence it quickly penetrates the skin and easily gets into skin fluids and blood. And then, Selamectin starts destroying fleas, flea larvae, flea eggs, and other parasites.

Selamectin is neurotoxic to parasites. It potentiates glutamate-gated chloride ion channels by increasing the permeability to chloride ions and hyperpolarization of nerve cells in parasites, thus causing the death by paralysis. It also potentiates other chloride channels, including the ones gated by gamma-aminobutyric acid (GABA).
