There are countless upsides to having a pet cat – but treating them for fleas is sadly a major, yet inevitable, part of the responsibility.
Fleas are no fun for cats. They can cause irritation and make your cat scratch, and can carry tapeworms and disease. They can also cause anaemia due to the amount of blood a cat can lose to parasites, and can even, in some cases, be fatal.
Using good, trusted flea treatments are the only way to ensure your cat stays flea-free. One of the most popular types of flea-treatments are spot on products, where a small pipette of liquid I applied to the back of the cat’s neck. They work in different ways and have different active ingredients, but they’re one of the best ways to ensure your cat stays free from fleas.
There are a lot of spot on flea treatments on the market, so here’s a simple breakdown of some of the best. Remember, it’s always best to speak to your vet about which products are safe to use for your cat in particular, and to read the label carefully before treating your cat.
The best overall flea treatment for cats
Kills: Fleas, ticks and lice | Formula: Vet-approved | Works: Within 48 hours | Suitable for: Pregnant cats
The Frontline spot-on treatment is an extremely popular topical flea treatment. Its ‘vet-strength’ formula is safe, fast-working and easy to apply.
Once treatment is applied, any fleas that dare to jump onto your cat will be killed within 24 hours, and ticks will be killed within 48 hours, which will prevent infestations. It also kills lice, which live and feed on a cat’s skin.
Like all spot on treatment, the formula is applied with a pipette, which makes it a bit easier for jumpy and restless cats who don’t like to make these sorts of things easy. Simply empty the contents of the pipette onto your cat’s skin at the back of their neck, so they don’t lick it off, and it will spread itself around.
The treatment comes in one, three and six-dose packs. One three-dose pack will provide your cat with three months of protection.
The formula can be safely used on kittens weighing more than one kg, from eight weeks old, including cats that are pregnant.
And as long as you don’t bathe your cat more than once a week, nothing should affect the efficacy of this popular product.
2. Beaphar Fiprotec Spot On solution
The best budget flea treatment for cats
Kills: Fleas and ticks | Works for: Five weeks | Active ingredient: Fipronil | Formula: Vet-approved
Beaphar Fiprotec Spot On solution is one of the better value options for flea treatments available on shelves and online today. It kills fleas and ticks on your cat as you apply it and for up to five weeks after that – although, it’s recommended you reapply the solution every four weeks, just to be safe.
The active ingredient in this formula is fipronil, which concentrates in the sebaceous glands on your cat, located at the base of the hair follicles, where it can constantly replenish the skin. The sebaceous glands store fipronil, which allows it to stay active for five weeks. But because of the nature of fipronil, it can take up to 24 hours for fleas and up to 48 hours for ticks to die.
This treatment contains six pipettes alongside an easy instructions guide, and is licensed by the Veterinary Medicines Directorate. It is suitable for all cats over eight weeks old, and who weight more than 1kg.
3. Bob Martin Clear Spot On
The best pesticide-free flea treatment for cats
Free from: Pesticides | Active Ingredient: Margosa | Kills fleas: Within 24 hours
If you’re looking for a pesticide-free way to save your cat from fleas, Bob Martin Clear Spot On is one of the most popular products of its kind on the shelves.
Instead of using a pesticide, the active ingredient in this flea treatment is margosa, an oil with a strong smell and taste that’s been used across Asia as a natural medicine for centuries.
The formula starts to kill fleas within 15 minutes of application, and promises to kill all the fleas hitching a ride on your cat within 24 hours. However, the treatment will only kill adult fleas that have settled on your cat, so it’s recommended you also apply it to your cat’s bed and around the home to prevent another outbreak.
Each pack contains six applications, and will protect your cat for up to four weeks, after which time you’re advised to reapply to ensure continuous protection. Although – you’ll have to reapply it sooner if your cat gets excessively wet.
4. RSPCA FleaAway Spot On Solution for Cats
The best flea treatment with donation
Works for: Eight weeks | Contains: Fipronil | Kills: Ticks and fleas
The RSCPA is a much-loved institution in the UK, helping to rescue and protect animals in need. Its FleaAway Spot On Solution works to control fleas for eight weeks after application, and ticks for up to four weeks.
The formula’s active ingredient is fipronil, a widely used broad-spectrum insecticide that disrupts the flea's central nervous system. However, fipronil doesn’t kill the eggs or larvae left behind in your home, so you may need to spray your house with a flea spray
Each product contains three treatments, alongside an easy-to-use pipette for straightforward application. It isn’t recommended for pregnant or nursing cats, and is suitable for kittens over the age of eight weeks and weighing more than 2kg.
As a nice bonus, 100% of the profits go to the RSPCA.
5. Frontline Plus Spot On Cat Flea Treatment
The best flea treatment for the home
Kills: Fleas, eggs and larvae | Lasts: Four weeks
If you’re looking for a flea treatment that really means business, you might want to try Frontline Plus spot on cat flea treatment.

Each treatment lasts for four weeks, preventing and treating flea infestations. It’s suitable for cats over the age of eight weeks.
