After dosing, it’s absorbed into the bloodstream; any flea that bites ingests the active and its nervous system is rapidly over-stimulated, leading to paralysis and death. Fleas start to die within 15 minutes, with more than 90% gone in six hours and complete eradication by 24 hours. Because the drug clears quickly, there’s no residue on coat or in the home, and it can be used alongside spot-ons or IGR sprays as part of a full flea-control programme. Suitable for cats and kittens over 4 weeks of age, between 1kg and 11kg. How to Use Give one tablet to any cat or kitten over 4 weeks and 1 kg when fleas are seen. Offer directly by mouth or hide in a small amount of food - ensure the full dose is taken . Do not exceed one tablet per day. Repeat on any subsequent day fleas are present. Combine with environmental control (vacuuming, household spray) and regular preventatives to stop re-infestation. Key Features Rapid Action: Kills fleas in 15 minutes; full kill within 24 hours. Oral Dose: No mess, no coat residue Combined Usage: Safe with spot-ons, collars, and home treatments Wide Suitability: From 4 weeks/1 kg; use in pregnant queens Veterinary Quality: Ideal for rapid knockdown in heavy infestations. Effective With One Dose: One tablet, repeat after 24 hours as needed. Johnson’s 4Fleas Tablets for Cats provide the quickest route to relief when fleas strike. Each small, easy-to-dose tablet contains nitenpyram, a veterinary-active molecule renowned for its speed: once swallowed, it is absorbed rapidly, and any flea that bites your cat ingests a lethal dose. Within minutes, fleas become hyperactive, stop feeding and begin to die; by six hours you’ll see the vast majority gone, and within 24 hours the infestation on your pet is effectively cleared. Unlike many topical preparations, 4Fleas Tablets leave no sticky residue, odour, or staining . There’s nothing to rub off on furniture, children, or other pets, making it a particularly convenient option for households where tactile contact with pets is constant. Because the active clears from the body within a day, you’re providing a sharp, targeted strike against existing fleas without committing your cat to a long-acting systemic treatment. That also means you can use the tablets alongside other products without concern, such as monthly spot-ons, collars, environmental sprays or foggers which may all be layered in to provide lasting protection and to break the flea life cycle in the home. Dosing is intentionally simple: one tablet treats any cat or kitten between 1 kg and 11 kg. Kittens must be at least four weeks old, but beyond that there are no contraindications: the product can be used in pregnant or lactating queens and in breeding cats. Administration is flexible: pop it straight into the mouth, or hide it in a morsel of food. If you still see live fleas the next day, you may repeat the dose. Fast kill is only half the battle. Around 95% of a flea population exists off the animal as eggs, larvae and pupae in carpets, bedding and upholstery. For true control, pair 4Fleas Tablets with regular vacuuming and an environmental product containing an IGR to stop immature stages developing. Wash or change pet bedding frequently, and treat all pets in the household, as untreated animals act as reservoirs that can re-seed the problem. Johnson’s 4Fleas Tablets are the ideal “first strike” in a comprehensive flea strategy: immediate relief for the cat, zero mess for you, and total flexibility to integrate with your year-round prevention plan . Keep a pack on hand so you can act the moment fleas appear, then follow up with ongoing measures to keep them from returning.

Never the ones from the vets are terrible. We used this for 2 years in the summer time and this is our second year of not having to treat our cats..... Hope I've helped  **Q: Active ingredient?** A: Keep away dont work **Q: Do these work to both prevent and kill fleas?** A: No they only kill adult fleas, they don't prevent **Q: Is it safe to give it to a cat in heat?** A: I'm afraid I'm unsure of that as I use them on my kitten who is just over 7 months old, so not a situation I have had to think about but I will check on the packet and see what it says and let you know, 👍 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Always use this brand *by R***E on 21 May 2026* I always order this brand as I find it works well for my cats .

No more flea dirt after her bath either so it probably did work. I recommend. However the packing takes too much space for just 3 tablets. ## Frequently Bought Together - Johnsons Veterinary Products 4Fleas Tablets for Cats and Kittens, Pack of 3 - Johnsons 4Fleas Tablets Large Dogs 3 Treatment Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/48123509-johnsons-veterinary-products-4fleas-tablets-for-cats-and-kittens-pack](https://www.desertcart.pt/products/48123509-johnsons-veterinary-products-4fleas-tablets-for-cats-and-kittens-pack) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-05*
