Johnson's 4Fleas | Cat Dual Action Flea & Lice | Spot On Treatment

Shopping Satisfaction
Bootstrap Example


Kill Fleas and Biting Lice (Trichodectes Canis) and protect against further infestation for 4 weeks with one easy application of Johnson's 4Fleas Dual Action Spot On.

The active ingredient, Imidacloprid, kills fleas within one day of treatment. Fleas tend to stop biting within a couple of minutes, so 4Fleas Spot On is ideal for minimising parasite related damage on cats suffering from Flea Allergic Dermatitis. Within 20 minutes of treatment, flea larvae around your pet (on their bedding, etc) will be killed.

Each pack contains 2 pipettes of 4Fleas Spot On, which will provide protection against both fleas and ticks for between 6 and 8 weeks.

The Small Cat option is for cats weighing under 4kg, and each vial contains 40mg Imidacloprid as active substance.
The Large Cat option is for cats weighing over 4kg, and each vial contains 80mg Imidacloprid as active substance..

Fleas are a common carrier of Tapeworm eggs, so if your pet has fleas it is important to treat them with a wormer such as Beaphar WormClear to target intestinal worms.

If your pet currently has fleas, it is important to treat their environment and other pets in the house for external parasites to prevent reinfestation. We don't recommend putting pets infested with fleas outside if they normally live indoors, as the fleas will begin to bite the human residents of the home. Instead, apply a fast-acting spot on such as Fiprotec and the fleas will begin to die as they bite the treated pet. In conjunction with treating the pets, Foggers and Sprays, infestations can be removed reasonably quickly.

All pet medicines must pass stringent testing to prove they are effective and safe before they are sold, regardless of whether they are available 'over the counter' or must be prescribed by a vet. All parasite control treatments available at Pet Connection have been proven effective and safe for pets, their owners and the environment, when used according to the instructions on the packaging. If you are concerned or unsure about the most suitable product for your pet, please feel free to contact us and we can provide information and advice.


Before you buy Beaphar FIPROtec® Spot-On, you'll need to know the weight and age of your dog so you can select the correct flea treatment. Beaphar FIPROtec® Spot-On is suitable dogs and puppies from 8 weeks of age and is available in four sizes.

Before use, read all the information provided in the box for full instructions. Hold the pipette upright and tap the neck section so the contents all fall into the body section of the pipette. Twist the cap to remove from the pipette then gently part the fur between your cat's shoulder blades. Gently squeeze the pipette to administer the product onto the skin.


This product is for use on cats and kittens over 8 weeks of age. Use on pregnant and lactating animals under veterinary supervision.

Active Ingredient: Imidacloprid.
