The 10 Best Flea Treatments for Kittens — Reviews 2021
1. Frontline Plus Cat/Kitten Flea Treatment — Best Overall
If you’re looking for the best flea treatment on the market today, you simply can’t beat Frontline Plus Cat & Kitten Flea and Tick Treatment. This long-lasting treatment remains active for 30 days after application and gets to work straight away to kill fleas and their eggs and larvae.
It’s also waterproof, so if your cat happens to need a bath, you don’t need to worry about this losing its efficacy. It’s suitable for cats and kittens over 8 weeks of age or weighing over 1.5 pounds. As well as killing fleas, this treatment also kills lice and ticks that can be vectors for Lyme disease.
2. PetArmor Flea & Tick Squeeze-On Treatment — Best Value
Our recommendation as the best flea treatment for kittens for the money is the PetArmor Flea & Tick Squeeze-On Treatment. Suitable for kittens over 8 weeks of age and 1.5 pounds in weight, this treatment is easy to use and gets to work killing those fleas straight away. While this is a great flea treatment, it missed out on our top spot because it only acts to kill adult fleas, not the eggs or larvae.
This spot-on treatment also kills ticks and lice within 72 hours of application. It’s waterproof, so it’s a good choice for cats who may have allergies and need a bath. This pack comes with three pipettes, equaling a 3-month supply.
3. Revolution Topical Flea Treatment — Premium Choice
If you’re looking for a premium choice for your kitten, then the Zoetis Revolution Topical Solution Flea Treatment is our recommendation. This kills adult fleas and prevents eggs from hatching, but it doesn’t affect the flea larvae, so you may need a few treatment cycles before you notice that all the fleas have gone.
Because this topical solution acts on heartworms, as well as fleas, you’ll need a prescription from your veterinarian. This is simple, and all you need to do when ordering is to add the contact details for your vet, so the order can be verified with them.
4. Onguard Flea & Tick Treatment
Onguard Flea & Tick Treatment kills fleas, flea eggs, and larvae, as well as chewing lice. This spot-on treatment can be used on kittens over 8 weeks of age, as long as they weigh more than 1.5 pounds. It contains two active ingredients designed to stop flea infestation while preventing future infestations.
This remains active for 30 days and is also waterproof, just in case your cat gets caught in the rain or needs a bath! You can choose from two different pack sizes: three or six treatments. The easy-to-use applicator has been redesigned and helps make sure that every drop of this treatment comes into contact with your cat’s skin.
5. Bayer Advantage II Flea Treatment
The Bayer Advantage II Flea Treatment has been specifically designed for kittens weighing between 2-5 pounds. This spot-on treatment contains two active ingredients designed to work together in order to kill all life stages of fleas. This pack includes two pipettes, each of which protects for up to 30 days.
This treatment is waterproof after 24 hours, so your kitten can have a bath if necessary, without you worrying that the treatment will stop working. Be sure to weigh your kitten carefully before use, as this is only designed for use in kittens who weigh over 2 pounds.
6. Sentry PurrScriptions Plus Flea & Tick Squeeze-On Treatment
The Sentry PurrScriptions Plus Flea & Tick Squeeze-On Treatment provides five-way protection from fleas, flea eggs, flea larvae, deer ticks, and mosquitoes. If you live in an area with West Nile Virus, then this is a great option as it’s effective on mosquitoes carrying West Nile.
Unlike most treatments, this spot-on shouldn’t be used on kittens under 3 months of age. So while it is an effective option, you’ll have to wait a little longer before you can use it on your tiny fur-baby.
7. Catego Flea & Tick Treatment
The Catego Flea and Tick treatment can be used on kittens over 1.5 pounds and at least 8 weeks of age. The topical, spot-on formula quickly gets to work and kills fleas in just 6 hours. It’s also effective against flea eggs, flea larvae, ticks, and lice. The patented applicator is designed to penetrate under your cat’s coat, so this treatment can be applied directly to your cat’s skin.
This is good value for money, and you can also buy this in a pack of one single treatment, which brings the cost down. This spot-on solution is quick-drying and non-greasy, but we can’t see any information from the manufacturer as to whether it’s waterproof after it’s been allowed to dry.
8. Capstar Flea Tablets
If your cat has sensitive skin and reacts to spot-on topical flea treatments, these Capstar Flea Tablets might be the answer. Of course, some cats can be a challenge to give tablets to! These tablets start working in just 30 minutes and are proven to be 90% effective at eliminating adult fleas in a matter of hours.
They’re suitable for kittens weighing 2 pounds and upward, so make sure you weigh your kitten beforehand to make sure they’re above that weight limit. These tablets can be given once a day if your cat has a serious infestation, and as they only kill adult fleas, you may need to treat your cat repeatedly until all the fleas have reached the adult stage of their life cycle.
9. Bravecto Topical Solution
If you’re looking for a long-lasting option for older kittens, this Bravecto Topical Solution is an excellent choice. It works for 12 weeks against fleas, meaning you can forget about those monthly spot-on reminders for a little longer. It doesn’t seem to be effective for 12 weeks when applied to kittens under 6 months of age, though, so if you do want to use this, we recommend waiting until your kitten is at least that age.
Bravecto is effective, but there have been reports of cats developing neurologic abnormalities after use. As you need authorization from your vet to order this product, we highly recommend speaking to them about whether this is a good option for your kitten.
10. Activyl Flea Treatment
Activyl Flea Treatment is a once-a-month spot-on treatment for kittens from 8 weeks of age that weigh over 2.9 pounds. You can choose from a pack of three or six treatments. This spot-on treatment is said to eliminate 90% of fleas within the first 12 hours after it’s been applied.
This is only effective against adult fleas, as far as we can tell. That means you’ll need to continue treatments while any remaining eggs and larvae develop into adult fleas. This also leaves an oily residue, which may take quite some time to dissipate.
Flea treatments have come a long way in terms of effectiveness, but how do you know what will suit your kitten best? We go over commonly asked questions to help you find the perfect solution for your new kitten.
Fleas can cause all sorts of problems for cats, including allergy dermatitis and bacterial infections, but they’re particularly nasty for kittens. Due to their small size, kittens are sensitive to anemia. So, if they lose too much blood from flea bites, their tiny bodies aren’t able to cope as well as those of adult cats. Kittens also don’t have a fully developed immune system, so they can be more susceptible to bacterial infections.
Before you choose any flea treatment, we recommend discussing your preferred option with your veterinarian to make sure it’s a good match for your kitten.
Taking the spot for the best overall flea treatment for kittens is the Frontline Plus Cat & Kitten Flea and Tick Treatment. Suitable for kittens over 8 weeks of age, this long-lasting and effective flea treatment is super easy to apply.
In terms of best value, the PetArmor Flea & Tick Squeeze-On Treatment can’t be beaten. This can last up to 6 weeks, but bear in mind that it only acts on adult fleas, not their eggs or developing larvae.
Whichever flea treatment you choose for your kitten, getting into a regular cycle of treatment means your kitten won’t be plagued by those uncomfortable biting insects and neither will you or your family! This leaves more time for everyone to enjoy those adorable kitten cuddles.
