Johnson's 4Fleas Dual Action Spot On for Cats

Johnson's 4Fleas Dual Action Spot On is a fast-acting, veterinary-licensed monthly treatment engineered to completely eradicate fleas and biting lice (Trichodectes Canis) on cats and kittens. Powered by the advanced active ingredient Imidacloprid, this easy-to-use topical spot-on targets parasites on contact without requiring them to bite your pet first. One simple application kills adult fleas within 24 hours and provides robust protection against further infestations for up to 4 weeks.

This dual-action formula is ideal for cats suffering from Flea Allergic Dermatitis (FAD), as the fleas typically stop biting within a few minutes of exposure to the treatment, drastically reducing scratching, skin irritation, and discomfort. Each pack contains 2 ready-to-use pipettes, providing a total of 8 weeks of continuous, stress-free protection for pet parents across Ireland & UK.

🚨 Crucial Advice: Why You MUST Treat Your House and Bedding

A very common mistake when tackling a flea problem is only treating the pet. If you apply a spot-on to your cat without treating your home, the infestation will quickly return. Here is the biological reason why environmental treatment is absolutely vital:

• The 5% Visibility Rule: Only 5% of a flea infestation actually lives on your pet at any given time (the adult fleas). The other 95% of the infestation lives entirely in your home—including your cat's bedding, your carpets, rugs, sofa cushions, and floorboard cracks—in the form of microscopic flea eggs, larvae, and pupae.

• The Hatching Loop: Adult fleas lay up to 50 eggs per day, which roll off your cat's fur directly onto their bedding and your carpets. Within 20 minutes of applying Johnson's 4Fleas, the active ingredient sheds into the immediate bedding to kill local larvae. However, thousands of hidden eggs and pupae in your carpets can remain dormant for months before hatching out into a wave of hungry new adult fleas.

• The Danger to Humans: If your cat has an active flea infestation, do not put an indoor cat outside thinking it will clear the problem. Deprived of their primary host, the newly hatching fleas in your carpets will immediately begin biting the human residents of the home instead.

How to clear the infestation permanently: To break the life cycle, you must treat your home environment simultaneously. Wash all pet bedding on a hot cycle (minimum 60°C). Thoroughly vacuum all carpets, rugs, and furniture to stimulate dormant pupae to hatch, then apply a high-quality household flea spray or fogger across all rooms. Ensure you treat all other household pets at the exact same time!

Directions For Use 💧

1. Weigh your cat accurately before application to ensure you select the correct weight variation.

2. Remove one pipette from the packaging. Hold it upright and gently tap the neck section so all liquid contents fall into the main body of the pipette.

3. Snip or twist off the top cap of the pipette.

4. Part your cat's fur at the back of the neck, right between the shoulder blades at the base of the skull, until the bare skin is clearly visible.

5. Place the tip of the pipette directly onto the exposed skin and squeeze firmly several times to empty the entire contents in one spot. Avoid applying to the surface of the hair coat, and ensure the liquid is applied in an area your cat cannot easily lick off.

Safety Warnings ⚠️

• Do not use on kittens under 8 weeks of age.

• Do not use on pregnant or lactating queens unless expressly supervised and approved by your veterinary surgeon.

• Never apply cat medications to dogs, rabbits, or any other animal species.

• The Flea & Tapeworm Link: Fleas are the primary carriers of tapeworm eggs. When your cat grooms and swallows an infected flea, it develops into an intestinal tapeworm infestation. If your cat currently has fleas, we strongly recommend treating them concurrently with an intestinal wormer, such as Johnson's One-Dose Wormer for Cats.

Frequently Asked Questions (FAQs) ❓

Does my cat need to be bitten for the flea treatment to work?

No. Johnson's 4Fleas Dual Action works on contact. The active ingredient spreads rapidly throughout your cat's natural skin oils, killing fleas as soon as they encounter the treated skin and coat, meaning they do not need to bite your pet to die.

Is this medicine safe to buy over the counter without a prescription?

Absolutely. All pet medicines stocked by Pet Connection undergo rigorous testing to prove environmental, human, and animal safety before receiving an over-the-counter retail license. When applied according to the enclosed instruction packet, it is incredibly safe and effective.

How long should I wait to bathe my cat after applying the spot-on?

It is recommended to avoid bathing your cat or letting them get wet for 48 hours after application to allow the active ingredient to spread completely through the skin layer.
