About Product
Hester Safeline Spot On for Cats by Hester Biosciences Limited is a cutting-edge veterinary topical ectoparasiticide formulated specifically for cats weighing between 2 and 10 kg, delivering a dual-action pharmaceutical assault on fleas, ticks, and biting lice while simultaneously disrupting the flea life cycle to prevent environmental reinfestation. Addressing one of the most persistent and health-threatening concerns for indoor and outdoor feline companions alike, Safeline Spot On combines Fipronil at 9.8% w/v and S-Methoprene at 11.8% w/v in a single convenient 0.5 mL pipette that is applied directly to your feline friend's skin, providing up to four weeks of continuous parasite protection and up to six weeks of flea egg and larval development inhibition. Where conventional flea treatments target only adult parasites, Safeline's dual-molecule strategy targets both the visible infestation and the invisible reservoir of immature life stages lurking in your pet's environment, making it one of the most complete and clinically intelligent ectoparasite solutions available for Indian cat owners. Animeal is proud to offer Hester Safeline Spot On for Cats as part of our trusted range of veterinarian-recommended parasiticide solutions for your feline companion.
Ingredients:
Fipronil (9.8% w/v): Fipronil is a broad-spectrum insecticide and acaricide belonging to the phenylpyrazole chemical class, developed in the late 1980s and now one of the most extensively validated ectoparasiticides in veterinary medicine globally. Following topical application to the skin between a cat's shoulder blades, fipronil is taken up into the sebaceous glands of the skin and redistributed continuously across the entire body surface through the skin's natural lipid secretions. This depot mechanism ensures that parasites are exposed to lethal concentrations of the active ingredient even when they land on parts of the body remote from the original application site. At the cellular level, fipronil exerts its insecticidal and acaricidal action by blocking the gamma-aminobutyric acid (GABA)-gated chloride channel complex in the insect and arachnid nervous system. GABA is the primary inhibitory neurotransmitter of the invertebrate central nervous system; by binding to and obstructing the GABA receptor-associated chloride channel, fipronil prevents the influx of chloride ions into neuronal cells, removing inhibitory control of nerve signalling. The result is uncontrolled neuronal hyperexcitation, manifesting as rapid convulsions and death in susceptible parasites including adult fleas (Ctenocephalides felis, Ctenocephalides canis), ticks (Rhipicephalus spp., Ixodes spp., Haemaphysalis spp.), and biting lice (Felicola subrostratus). Critically, fipronil's selectivity for invertebrate GABA receptors over mammalian receptors is approximately 700 to 1,300 times greater, underpinning its excellent safety profile in cats when used at the recommended dose.
S-Methoprene (11.8% w/v): S-Methoprene is a juvenile hormone analogue (JHA), a class of insect growth regulators (IGR) that mimics the structure and biological activity of juvenile hormone, a naturally occurring hormonal compound that regulates insect development. In the flea life cycle, juvenile hormone must decline to undetectable levels for an immature flea to successfully complete metamorphosis and emerge as a biting adult. S-Methoprene artificially maintains elevated juvenile hormone levels throughout the development of flea eggs and larvae, pharmacologically preventing the hormonal transition required for pupation and adult emergence. Fleas whose eggs or larvae are exposed to S-Methoprene either fail to hatch, fail to develop beyond the larval stage, or die before completing metamorphosis. S-Methoprene has no adulticidal activity against fleas or any effect on ticks; its role is exclusively to break the generational cycle of flea reproduction, addressing the 95% of the flea population that exists as eggs, larvae, and pupae in the environment rather than on the host. By inhibiting flea egg development for up to six weeks following application, S-Methoprene ensures that even fleas that briefly contact the treated cat cannot successfully seed a new infestation in the household. Importantly, S-Methoprene is selectively active only in invertebrates, as mammals lack juvenile hormone entirely, giving it an exceptional mammalian safety profile.
Features and Benefits
Dual-Molecule, Whole-Life-Cycle Flea Eradicatio...
Dual-Molecule, Whole-Life-Cycle Flea Eradication:
Safeline Spot On targets fleas through two completely independent mechanisms simultaneously, making it one of the most comprehensive flea control solutions available for your feline companion. Fipronil rapidly eliminates adult fleas, ticks, and biting lice already on your cat within 24 to 48 hours, while S-Methoprene simultaneously dismantles the next generation of infestation by preventing flea eggs and larvae from developing into biting adults, breaking the cycle of reinfestation at its biological root.
Up to Four Weeks of Continuous Adult Parasite Protection:
A single 0.5 mL pipette application provides your feline friend with up to four weeks of uninterrupted protection against adult flea and tick re-infestations. Fipronil's accumulation in and redistribution from the skin's sebaceous glands creates a self-renewing reservoir of active ingredient at the skin surface, ensuring that any flea or tick that contacts your cat's coat after application is exposed to lethal concentrations of the parasiticide.
Six Weeks of Environmental Flea Life Cycle Disruption:
By incorporating S-Methoprene as an insect growth regulator, Safeline Spot On extends its protective reach far beyond the pet and into your home environment. Flea eggs shed by treated cats carry residual S-Methoprene into bedding, carpets, and furniture, where they fail to develop, dramatically reducing the environmental flea burden that is responsible for persistent, recurring infestations in households with cats.
Effectively Manages Flea Allergy Dermatitis (FAD):
For cats suffering from flea allergy dermatitis, a hypersensitivity condition triggered by proteins in flea saliva that causes intense pruritus, alopecia, and secondary skin infections, Safeline Spot On alleviates the root cause by rapidly eliminating the flea population and preventing new infestations. Regular monthly application reinforces a flea-free skin environment, reducing the frequency and severity of FAD episodes in sensitised feline companions.
Selectively Safe for Cats with a High Mammalian Safety Margin:
The selectivity of Fipronil for invertebrate GABA receptors over mammalian receptors, and the complete absence of a mammalian juvenile hormone target for S-Methoprene, together provide a wide safety margin that makes Safeline Spot On well tolerated in cats at the recommended application dose. Manufactured and marketed by Hester Biosciences, a company with a decades-long track record in Indian veterinary pharmaceutical production, the formulation meets rigorous quality standards as required for licensed veterinary medicines in India.
Simple Monthly Application for Year-Round Protection:
The single-use pipette format makes Safeline Spot On straightforward to apply and virtually stress-free for both pet and owner, requiring only one application per month to maintain continuous protection. For cats living in high-infestation environments, those with outdoor access, or those in multi-pet households where reinfestation risk is elevated, year-round monthly application is the preferred protocol recommended by veterinarians to maintain a consistently flea-free and tick-protected feline companion.
Usage and Applications

How to Use:
Hester Safeline Spot On for Cats is for external use only and must be applied by parting the fur at the base of the skull, between the shoulder blades, directly onto the exposed skin. Remove the pipette from its packaging and hold it upright. Snap or twist off the cap as directed on the packaging. Part your feline companion's fur carefully to expose a clear area of skin and apply the entire contents of the pipette directly onto the skin in a single spot. Avoid spreading the solution over a wide area. Do not apply to broken, irritated, or inflamed skin. Use one pipette per application for cats weighing between 2 and 10 kg, once per calendar month. Do not apply more frequently than once monthly. Avoid allowing the product to contact the cat's eyes, mouth, or mucous membranes. Do not allow the cat to groom the application site immediately after treatment; if treating multiple cats, keep them separated until the application site is fully dry to prevent mutual grooming and inadvertent ingestion. Wash hands thoroughly with soap and water after handling the pipette. This product is for use on cats only and must never be applied to rabbits or other species. Do not allow children to handle treated cats until the application site is fully dry. Do not bathe the cat for 48 hours before or after application to ensure optimal absorption and efficacy.
Storage Advice:
Store unopened Hester Safeline Spot On for Cats in a cool, dry, and dark place below 25°C, away from direct sunlight and moisture. Do not freeze. Keep the pipette in its original sealed packaging until the time of use. Store out of reach of children and away from food, drink, and animal feed. This product is a veterinary parasiticide; handle and store accordingly. Do not use after the expiry date printed on the pipette or outer packaging.
