FRONTLINE® SPOT ON keeps your cat comfortable, happy, and free from parasites, giving you peace of mind and your pet a healthy, itch-free life.

Instructions

How to administered?

Part the cat’s fur at the base of the neck until the skin is visible. Place the tip of the pipette on the skin and squeeze to empty the contents completely onto the skin.

Frequently asked questions

What is FRONTLINE Spot-On for Cats used for?
FRONTLINE Spot-On for Cats is used to treat and prevent flea infestations and to control ticks. It also helps treat biting lice.
How does FRONTLINE Spot-On work?
It contains fipronil, which spreads across the skin and coat after application. It kills fleas and ticks on contact.
How long does one pipette last?
One application protects against fleas for up to 5 weeks and against ticks for up to 2–4 weeks, depending on exposure.
How often should it be applied?
Apply one pipette every 4 weeks for continuous protection.
How do I apply FRONTLINE Spot-On to my cat?
Apply directly to the skin at the back of the neck, where your cat cannot lick it. Ensure the coat is parted so the solution reaches the skin.
Can I bathe my cat after applying it?
Avoid bathing for at least 48 hours after application. Frequent washing may reduce the duration of protection.
Is it safe for kittens?
It can be used in kittens from 8 weeks of age, provided they meet the minimum weight requirement stated on the label.
Does FRONTLINE Spot-On protect against worms?
No. It does not treat intestinal worms or heartworm. A separate worming treatment is required.

Do I need a prescription to buy POM-V pet medicines online?

Yes. POM-V items require a valid prescription from your UK vet.

 Upload your prescription during checkout. 

Photos must be clear. If details are wrong or expired, orders can’t be processed. This is standard across UK pet pharmacies.

No. Under UK law, vets must provide a written prescription if you request one for a POM-V medicine. They may charge a reasonable fee for issuing it, but they cannot refuse. This allows you to choose where to buy your pet’s medication, whether directly from your vet or from a registered UK pharmacy such as Ashcroft 4 Pets.

In the UK, most POM-V prescriptions are valid for 6 months, unless your vet specifies a shorter duration. Prescriptions for Schedule 2 or 3 controlled medicines are usually valid for 28 days and are not repeatable. At Ashcroft 4 Pets, we follow these same UK veterinary guidelines to ensure your pet’s medication is dispensed safely and legally.

At Ashcroft 4 Pets, we are a fully VMD-registered and accredited online retailer. This means every prescription and over-the-counter pet medicine we supply is safe, genuine, and dispensed according to UK law.

We follow all Veterinary Medicines Directorate (VMD) rules, and our team checks every prescription carefully before processing. You can order with confidence, knowing your pet’s health is in the hands of experts and all medicines are traceable, legally supplied, and authentic.

In the UK, most repeat prescriptions for POM-V medicines are valid for up to 6 months from the date your vet issues them. You can order multiple times within this period if your vet has authorised repeats.

For controlled medicines (Schedule 2 or 3), the prescription is valid for 28 days only and cannot be repeated. These medicines are strictly regulated due to their potential for misuse.

At Ashcroft 4 Pets, we follow UK law carefully, ensuring all prescriptions are dispensed safely, legally, and in the exact amounts prescribed.

 If your vet prescribes a human medicine for your pet under the Cascade, we can usually dispense against that prescription (with the right checks).
