Q & A

Below are some recent questions we've received regarding FRONTLINE Spot On Flea & Tick Treatment Dogs & Cats, including answers from our team.

18 June 2025 at 2:36pm

Large cat

Caroline

Will this treat a large cat of 11 kilos?

  • VioVet Staff

Dosage: The recommended dosage is based on weight ranges, so for a cat between 1-10 kg the dosage is 0.5 ml per cat, which is approximately 7.5–15 mg/kg.

For a cat over 10 kg, you may need to consult your veterinarian to determine whether an increased dose is necessary or if a different product is more suitable for the weight of your cat.

How many pipettes for weight of cat?

Mc

How many pipettes do you use per treatment please? I recall a cats weight being important. Many thanks

  • VioVet Staff
  • The entire pipette is applied once monthly to the skin at the base of the neck.

  • Do not use more than one pipette at a time unless instructed by a vet.

How can I prevent fipronil destroying insect populations?

Chris

Fipronil has been implicated in the crash of insect populations including bees and other vital pollinators, is there a way to safely use this product without it getting into the water cycle and destroying the wildlife?

  • VioVet Staff

The safest and most recommended method is to return any unused or expired Frontline products to your veterinary clinic or pharmacy. They have proper disposal methods in place. Please see our website for more information on returns.

I have given my cat Frontline Spot On. Can I also give him Prazitel wormer at the same time?

Katherine

  • VioVet customer since 2021
  • From: Cornwall, United Kingdom

I have given my cat Frontline Spot On. Can I also give him Prazitel wormer at the same time?

  • VioVet Staff

Yes, these two products are safe to use at the same time. If it is the first time using one or both of them then I suggest using them apart. This is so that if the rare case of a reaction occurs you can deduce which product triggered it.

Shelf life

Sarah

What will the minimum shelf life be of medications at time of purchase?

  • VioVet Staff

Our Terms and Conditions guarantee that expiry dates will be longer than the medication is required for, at least 6 months from the date of issue. It is therefore not advised to order more than 6 months worth of medication as we cannot replace/refund any medications that expire longer than 6 months from the date of delivery.
Most of our medications have expiry dates of at least a year from the date of delivery however we can only send what our supplier send us, which does vary.

Treating two dogs together

Barney and buster

Is it ok to treat two 1 year old brother Labradors together we can’t they will not play together may get it in there mouth

  • VioVet Staff

It is recommended to prevent licking of the area the spot on has been applied. The product should dry significantly within a few hours so separation for only a short period should be necessary.
If the product is licked off then it will not work effectively and some side effects may be seen.

Frontline vs ADVOCATE

Jojo Furnival

  • VioVet customer since 2022
  • From: Herefordshire, United Kingdom

My dog and I have moved to the UK from Australia where I always treated him with Advocate for flea and tic prevention. I understand that I can't get that in the UK without a vets prescription. So my question is, what's the difference between frontline and Advocate - and is frontline as effective?

  • VioVet Staff

Frontline contains fipronil and protects against fleas, lice and ticks.
Advocate contains moxidectin and imidacloprid which protects against fleas, lice, mites and roundworms (including lungworm). Advocate does not protect against ticks, but Advantix does.
Frontline and Advocate actually have slightly different coverage and it is not possible to say that one is better than the other.
If you would like further worming advice then I advise contacting us on [email protected] or chatting to your local vet.

I NEED A TABLET FOR FLEA AND TICK treatment for my DOG

  • VioVet Staff

Unfortunately there are no over the counter preventative flea/tick tablets in dogs. You can use Capstar for fleas however this will only work for 24 hours or so and not have any long lasting preventative effect.
If you need a tabletable preventative flea/tick treatment for your dog then you will need a written prescription from your vet for suitable products such as Bravecto or NexGard.

How many

Bridget

how many pipettes are there in a pack ?

  • VioVet Staff

This depends on the size of the pack you purchase. They come in 1, 3 or 6 pipette packs.

Ear mites

M

Will this kill ear mites in cats?

  • VioVet Staff

This product is not licensed against ear mites in cats. Only prescription wormers, such as Advocate, are licensed to do this. You can purchase these from us but you will need a written prescription from your vet to do so.
